Reply to comment by TheBloxyBloxGuy in Is there a fertile creature with an odd number of chromosomes? by TheBloxyBloxGuy

Do a general search for sex-determination systems. There are all sorts of patterns that can arise from other systems that aren’t XY.

In particular ZO/ZZ sex determination where the female only has one sex chromosome and the male has two.

It only occurs in some species of moth though.

Not relevant to the original topic but it blew my mind when I found out that there are mushrooms with thousands of sexes. Super weird little fungi :)

Yea Fungi mating types aren’t so much sexes as we understand them and more decoder rings.

It’d be like if we had 4 sex chromosomes instead of two, and multiple letters instead of binary.

XAYZ sex vs LBXK sex, and you can only mate with someone whose every chromosome is different.

That, in very broad strokes, is the method behind some fungi reproduction. Others are pretty analogous to human sexes. It’s a very wide range of strategies with fungi.

I see why mycologists claim there are thousands of unidentified species of fungi. It makes sense that many variants would occur.
