Hello everyone!
I was revising today, and realised basically I understand why there is the first cell division in meiosis. But why have a 2nd?
The first stage created 2 haploid cells as far as I can make out, and then by dividing again, doesn't the 4 cells just get one chromatid from each chromosome? How does this work, and surely when they fuse in fertilisation there would just be two lots of 23 chromatids fusing, whereas what is wanted is two lots of 23 chromosomes fusing in fertilisation to get 23 homologous pairs?
What am I missing?
Any help appreciated, thanks!
