Does crossing two monokaryotic parents multiple times result in the exact same child genotype?
    #28432429 - 08/13/23 02:11 PM (5 months, 12 days ago)

Let's say you have two monokaryotic cultures, A and B. You transfer twice from A and twice from B making two separate crosses A1+B1 and A2+B2, where the parent genotypes are the same in both cases; are the two children the exact same child genotype?

Not technically a parent but a monokaryotic culture by definition will have the same set of genes across the entire culture.

What my question pertains to is when having two (different) monokaryotic cultures and combining them to create a dikaryotic culture; if one were to combine the same two monokaryotic cultures into another dikaryotic culture on a different petridish, would the two dikaryotic cultures be identical genotypes?

My point is that whatever genetic expression is available on one side of the initial monokariote would be available on the other.

Therefore the same potential genetic crosses are available across either plate.

I don't know much about how mieosis is done in fungi, and I vaguely remember something about monokariotic cultures struggling to join at times, I think they prefer to join immediately. " In meiosis, four haploid cells are produced. Each haploid cell has half the chromosome number of the parent cell. However, in fungi, meiosis occurs right after two haploid cells fuse, producing four haploid cells.Feb 29, 2012
https://www.ck12.org › section
Fungi | CK-12 Foundation"
but take that with a grain of salt

From what I know about meiosis in animals half of the parent chromosomes are "chosen" at random and since we have 46 chromosomes that would be 23x23 possibilities, right? Or 529.

Cubensis has fewer, but genetics of fungus seems not very studied.

Do some research on mieosis and fungal cell division
