So, I was thinking... If you were to cultivate some mushrooms and had a successful grow take a print, then try another flush. Do the genetics change from the second flush? Like a tree, take a seed from a tree, plant it. That seed turns to a tree then produces seeds, then take them seeds and plant them.. Your trees genetics will be weakened,
when trying to re-vegetate a bushland area its better getting the same seeds from different trees making it more diverse, back to the question do the mushrooms on one cake each have their own genetics or all the same? And do they get weakened over time?
Thankyou!

I'm not sure what you are asking? Fungal lifecycle. If you have sexual reproduction, then yes you will have a new mutated organism. This means that yes - it will be different from the parents, but different does not necessarily mean worse.
If you want asexual reproduction you can take clones.

lets say you have one syringe left! Can you cultivate and take another print multiple times I mean like 4 to 5 times without potency or growing effected?

read any one post about genetics there is probaly 100,000 of them.

Yes. The thing is a spore print isn't like a seed. It's more like millions of seeds that bind together. The genetics don't decrease. There won't be in breeding as new genetics are formed during each print. Potency won't be effected either. Flushes do have completely different genetics and that could effect potency on a MS.

Every print is a fresh slate. No worries!

and this is all I needed I know I confused others by explaining it with a tree, know a tree is nowhere near the same as fungi!
Thankyou sir!

Maybe off of topic but if you grow a true isolate would you still get a few flushes or just one flush?

I've read that you should still get multiple flushes. I don't know personally I've never worked with isolates so IDK

I disagree. In the wild, cubensis has the full complement of genetics that are available in the wild. Tautology Club President
Not so in your average print. This is because in a lab setting, including your house, certain traits are selected for and very quickly a lot of the diversity gets weeded out. A good example of this is the Purple Mystics, a pretty obscure variety out of Florida which have a mutation that was difficult to isolate. But essentially the gist was that the cap was very hygrophanous, which meant that when it got wet it became translucent. With a purple-spored species like Psilocybe cubensis, this translated to a cap that had a purple ring around the outside when it was really wet and the lighting was bright.

There were a few mixed grows, and the trait popped up every now and then along with a bunch of other weird mutations. One grower (claybuddy) had a bunch of umbonate and subumbonate caps that were all sterile. No spores at all.
 
Pretty obviously, sterility was a trait (or traits) passed on from the wild print and which selected itself out of existence. There were a few reported purple-ringed caps here and there, but those too were lost. Probably this has something to do with accidental selection, because we select for a few things offhand, without even thinking about it: fruiting ability in a low-FAE environment, spore production (nobody wants to send a shitty, light print), paying less attention to the traits that we really want to preserve. So through this process we have a pretty good illustration of how the genetics can decrease. And intuitively we know this to be true, even though there's a lot of misinformation on the shroomery about the subject. After all, if you have a complete reset every time a spore print drops, there can be no selection. This is a roundabout way of saying that you believe fungi are immune to evolution.
People who really know what they're doing can preserve those traits in a process called stabilization. And eventually, when too much inbreeding has been done, the lineage becomes unstable--just like in anything else--and eventually dies out because of the accumulation of crap genetics. And in fact a lot of the old original varieties of cubensis are defunct now because of this. So in sum, OP was right in that a spore is kind of like a seed, and selection can occur both artificially and naturally, but he didn't know that by the time he gets his hands on a print most of the variation has been bred out of it.

So in the wild how would these spores stay fertile. I thought of it as each strain in a MS as a genetic set that would combine in the mushrooms. The spores would take each strains traits and when they combine and form mycelium. I know that certain traits would be weeded out over time but that the sexual diversity would keep the cultivation of mushrooms alive. But I'm not that advanced in mycology. I've just been trying to understand the works of it.

The trait survives in the wild for probably a few reasons. For one, it does a lot less inbreeding in the wild. For another, heterozygosity might convey some advantage for some reason that I absolutely don't know or understand, but which might bear a resemblance to the genetic propensity toward heterzygosity for sickle-cell anemia in regions with high malaria rates.
Each spore carries half the genetic information of the total. When it germinates, it forms a mycelial network which has one nucleus--it's monokaryotic. If it finds a compatible partner, they'll swap nuclei and become a dikaryotic strain with two separate nuclei in the same cell, existing alongside each other until the time comes to do some recombinance and they switch from being essentially 2 x haploid to diploid for the whole crossing-over and meiosis thing.
I don't understand the rest of your question.
