Current Question (ID: 15438)

Question:

The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis is

Options:

1. spermatocyte - spermatogonia - spermatid - sperms
2. spermatogonia - spermatocyte - spermatid - sperms
3. spermatid - spermatocyte - spermatogonia - sperms
4. spermatogonia - spermatid - spermatocyte - sperms

Solution:

In spermatogenesis, during growth phase some spermatogonia either due to growth or due to food storage become 2 or 3 times larger of their original size and are known as primary spermatocytes, which undergo meiosis-I and as a result 2 haploid secondary spermatocytes are formed. Further, meiosis-II takes place that results in the formation of 4-spermatids. Then, these round, non-motile and haploid spermatids are transformed into thread-like motile, haploid sperms (four).
