what makes 2 different p. cube strains different from each outher?

lets use B+ an PE as an example. There both p cubes, but b+ has hollow stems, and PE looks like a cock.

If they are the same species why are they so differnt from each other.


If there is a link explaining the difference in strains please post it because i cant find much on the subject and im curious about it.

If I was to go hunting in the wild would i be able to find a pe strain or b+, or were they created in a lab?

Genetics. Look at a Pygmy from Africa next to an NBA player from Croatia, yet they're both humans. Look at a poodle next to a german shepard, etc. There's also lots of variation within each strain. Not all PE's look alike. Ditto for all the strains.

There are sub strains of P. Cube kind of like chile peppers have diffent 
strains or like the Cat famliy there big cats and theres small house cats
like you can mix two diff cats loin and a tiger(you kown how :wink:) and get a loinness but it can't make babys. Most strains whore gown out by "labs"
    P. Cube
          /\
    PE  B+
    /\    /\
Newstrins
Evey time a two spores meat up (kind of like us humans :smirk:) they make up a new strain.
Do a :google:to look up more
Hope this halps, Do I have this right ?

This is not a good example, since many chilli peppers stem from different SPCECIES, they are not all just different strains of the same species.

>or like the Cat famliy there big cats and theres small house cats

Again, very bad example, you are talking different species here. A lion can't mate with a house cat and produce fertile offspring.

Re: strains(Binomial nomenclature) [Re: Anno]

Look it the binomial nomenclature name(an formal method of naming species)
The cat, also called the domestic cat or house cat, is a small feline carnivorous mammal of the subspecies Felis silvestris catus.
Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Felidae
Genus: Felis
Species: F. silvestris
Subspecies: F.s. catus
The domestic cat was named Felis catus by Carolus Linnaeus in his Systema Naturae of 1758. Johann Christian Daniel von Schreber named the wild cat Felis silvestris in 1775. The domestic cat is now considered a subspecies of the wild cat: by the strict rule of priority of the International Code of Zoological Nomenclature the name for the species thus ought to be F. catus since Linnaeus published first. However, in practice almost all biologists use F. silvestris for the wild species, using F. catus only for the domesticated form.

In opinion 2027 (published in Volume 60, Part 1 of the Bulletin of Zoological Nomenclature, 31 March 2003 [19]) the International Commission on Zoological Nomenclature "conserved the usage of 17 specific names based on wild species, which are predated by or contemporary with those based on domestic forms", thus confirming F. silvestris for the wild cat and F. silvestris catus for its domesticated subspecies. (F. catus is still valid if the domestic form is considered a separate species.)
Johann Christian Polycarp Erxleben named the domestic cat Felis domesticus in his Anfangsgründe der Naturlehre and Systema regni animalis of 1777. This name, and its variants Felis catus domesticus and Felis silvestris domesticus, are often seen, but they are not valid scientific names under the rules of the International Code of Zoological Nomenclature
Lions have also been known to breed with their close counterparts, tigers (most often Amur), while in captivity to create interesting mixes. These two new breeds are called ligers and tigons.

The liger originates from mating a male lion and a tigress. Because the lion passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female lion is not present, ligers are larger than either parent. It is said that ligers do not stop growing and will grow constantly through their lifespan, until their bodies cannot sustain their huge size any longer, reaching up to half a tonne. Ligers share some qualities of both their parents (spots and stripes) however they enjoy swimming, a purely tiger activity, and they are always a sandy color like the lion. Male ligers are sterile, but female ligers are often fertile.

The tigon is a cross between the lioness and the male tiger. Because the male tiger does not pass on a growth-promoting gene and the lioness passes on a growth inhibiting gene, tigons are often relatively small, only weighing up to 150 kilograms (350 lb), which is about 20% smaller than lions. They can best be described as "housecat-like" in appearance, although with round ears. Like male ligers, male tigons are sterile, and they all have both spots and stripes, with yellow eyes. Tigons are not as common as ligers because they are more difficult to produce since male tigers are less attracted to lionesses because of their smaller size and are thought to have difficulty with recognizing lioness breeding cues.

Female ligers and female tigons are fertile and can produce offspring if mated to either a pure-bred lion or a pure-bred tiger. Such inter-breeding was a practice earlier, but has been stopped now.


The most common species of chile peppers are:

Capsicum annuum, which includes many common varieties such as bell peppers, paprika, jalapeños, and the chiltepin
Capsicum frutescens, which includes the cayenne and tabasco peppers
Capsicum chinense, which includes the hottest peppers such as habaneros and Scotch bonnets
Capsicum pubescens, which includes the South American rocoto peppers
Capsicum baccatum, which includes the South American aji peppers

Assorted paprika fruits from MexicoThough there are only a few commonly used species, there are many cultivars and methods of preparing chile peppers that have different common names for culinary use. Green and red bell peppers, for example, are the same cultivar of C. annuum, the green ones being immature. In the same species are the jalapeño, the poblano, ancho (which is a dried poblano), New Mexico, Anaheim, Serrano, and other cultivars. Jamaicans, Scotch bonnets, and habaneros are common varieties of C. chinense. The species C. frutescens appears as chiles de arbol, aji, pequin, tabasco, cayenne, cherry peppers, malagueta and others.

Peppers are commonly thought of as being broken down into three groupings; bell peppers, sweet peppers, and hot peppers. Most popular pepper varieties are seen as falling into one of these categories, or as a cross between them

In biology, binomial nomenclature is the formal method of naming species. As the word "binomial" suggests, the scientific name of a species is formed by the combination of two terms: the genus name and the species descriptor. Although the fine detail will differ, there are certain aspects which are universally adopted:

Scientific names are usually printed in italics, such as Homo sapiens. When handwritten they should be underlined.
The first term (genus name / generic name) is always capitalized, while the specific descriptor (in zoology, the "specific name", in botany, the "specific epithet") will not be, even when derived from a proper name. For example, Canis lupus or Anthus hodgsoni. (But note that this is a modern convention: Linnaeus always capitalized the specific descriptor, and up to the early 20th century it was common to capitalize the specific descriptor if it was based on a proper name.)
When used with a common name, the scientific name usually follows in parentheses, for example, "the house sparrow (Passer domesticus) is endangered."
The scientific name should generally be written in full when it is first used or when several species from the same genus are being listed or discussed in the same paper or report. It may then be abbreviated by just using an initial (and period) for the genus; for example Canis lupus becomes C. lupus. In rare cases this abbreviation form has spread to more general use — for example the bacterium Escherichia coli is often referred to as just E. coli, and Tyrannosaurus rex is perhaps even better known simply as T. rex.
The abbreviation "sp." (or "spec.") is used when the actual specific name is not known: for example Canis sp. denotes "a species of the genus Canis". The abbreviation "spp." (plural) indicates "several unknown species".
The abbreviation "cf." is used when the identification is not confirmed: for example Corvus cf. splendens indicates that the species is in doubt.
The value of the binomial nomenclature system derives primarily from its economy, its widespread use, and the stability of names it generally favors:

Every species can be unambiguously identified with just two words.
The same name can be used all over the world, in all languages, avoiding difficulties of translation.
Although such stability as exists is far from absolute, the procedures associated with establishing binomial nomenclature tend to favor stability. For example, when species are transferred between genera (as not uncommonly happens as a result of new knowledge), if possible the species descriptor is kept the same. Similarly if what were previously thought to be distinct species are demoted from species to a lower rank, former species names may be retained as infraspecific descriptors.
Despite the rules favoring stability and uniqueness, in practice a single species may have several scientific names in circulation, depending largely on taxonomic point of view (see synonymy).

A major source of instability is the resurrection of forgotten names, which can claim priority of publication. In this case, however, conservation according to the nomenclature Codes is possible

Genetics? Or DNA?

Would the theory of dominant and recessive traits also apply to mushrooms?

Of course. Mendelian inheritance applies to all life based on double stranded DNA, that is to say all life that we know of.

Regarding "sub strains"(which is not a necessarily accurate description for phenotypic variation within a species).

Substrains are reference to allele variation within a species (i.e. Psilocybe cubensis). Alleles are the term used for a specific genetic trait, they are in essence, genes, however within one parent organism, there may be different alleles(traits) for the same gene. In the case of animals including humans, each parent has two alleles of one gene. If one parent has lets say, a blue and a brown allele for the eye colour gene (lets assume only ONE gene influences eye colour for simplicity), brown eye colour is the dominant allele to blue. What a dominant allele means versus a recessive allele, is that the dominant allele will be the one that is phenotypically expressed. Phenotype refers to the active or apparent allele, rather than the dormant allele (blue eye colour) which will not be expressed because the dominant brown allele inhibits it. The parent with brown eyes, yet having a blue allele and a brown allele, is said to be a "carrier" of the recessive allele(blue).
When two parents produce offspring, each parent randomly passes one of their two alleles of a gene to the offsrping- either the blue or the brown. Lets say that the other parent also has brown eyes, this means that we can assume that the parents has ATLEAST one brown allele, because brown is the phenotype, and the only way to express brown eyes, is to have atleast one brown allele. This parent could also have a blue or green recessive allele, or they could have two brown alleles, which would still express itself as brown. If the parents produce offspring, the ofspring could recieve both dominant brown alleles, one brown dom. allele, and one blue rec. allele, which would produce brown eye colour, OR they could get one blue rec. allele from each parent, and without a brown dom. allele to mask the blue trait, the child of two brown eyed parents could produce a blue eyed child.
With "strains" or "substrains", often the less adaptive trait will hinder the organism, and the organism may die before reaching reproductive maturity, thus it would not pass on it's maladaptive alleles to the next generation. This phenomena if referred to as Natural Selection, and it often works well for the species, allowing only the best traits to be passed on. This is all relative to environment, and the environment will select for specific traits that are beneficial for the organism in its environment. This is why you do not sea animals with dense fur such as a polar bear in Africa- because those traits which help the animal to survive extreme colds, are maladaptive in its survival in the hot savanna of Africa, and it would die.

When you see consistent phenotypical variation between two geographical populations of the same species (as in the case of P. cubensis), it is because natural selection has selected for or against certain traits, and often certain traits may become extinct within one population, where another population of the same species may commonly express the trait that became extinct in the other group. Because both members of the two populations are of the same species, they are able to breed and produce offspring, with some traits familiar to both populations(strains).

exactly - certain conditions reinforce certain phenotypical traits.
