All but one of the following statements are true regarding the differences between early and late spermatids. select the answer below that does not reflect a difference between early and late spermatids.
a) early spermatids are round and have excessive cytoplasm.
b) early spermatids have not undergone meiosis and are still diploid.
c) early spermatids have not undergone spermiogenesis.
d) early spermatids have not formed a flagella.

B) Early spermatids have not undergone meiosis and are still diploid.

Explanation:

Spermatids are formed at the end of meiosis in the testes of male. Spermatids are haloid cells in which chromosome numbers are half as compared to their parent cells. An early spermatid has not undergone morphologic changes and is considered less mature than the late spermatid.

Late spermatids undergo morphological changes (spermiogenesis) and they transform into a spermatozoa which is ready to release in the lumen.
