A sex cell is haploid. It has half the number of chromosomes.How does the number of chromosomes in a sex cell compare with that in a parent cell?
In humans, it's half. Not sure if that holds for ALL sex cells in every single animal.How does the number of chromosomes in a sex cell compare with that in a parent cell?
For all cells which go through sexual reproduction, the sex cells are haploid, or half. If the organism goes through asexual reproduction or a cycle of sexual alternating with asexual, this differs. In asexual reproduction, the number of chromosomes, does not need to be half, because rather than the combination of two completely different cells, rearrangement or partial transfer/trading of chromosomes from one cell to another occurs.
