what would be the number of chromosomes in spermatids?
Spermatids have half this number, for a total of 23 chromosomes. Each chromosome is composed of only a single chromatid following division, for a total of 23 chromatids. When the zygote is formed during the fusion of the sperm and egg cells, the final cell is diploid, containing 46 chromosomes (23 from each gamete).
