During crossing-over

When does apoptosis occur?

If a crayfish has 200 total chromosomes in its body cells (not ovaries or testes)

It is the secondary oocyte and not the egg that the sperm fertilizes to form a diploid organism.

The only haploid stage in the animal life cycle is the gamete.

Meiosis results in a change in chromosome number indicated by
