How are spermatogonia formed from stem cells?
The immature cells called spermatogonia are formed from these stem cells. The stem cells divide mitotically of which, the first half develop to form sperm cells, whereas the rest remain as stem cells to provide a continuous flow of stem cells in the tubules. These cells then migrate towards Sertoli cells.
How are paternal and maternal genes exchanged in spermatogenesis?
By chiasma formation mutual exchange of some chromosome material between two non-sister chromatids of each homologous pair (tetrad) occurs (crossing over) to provide an almost indefinite variety of combinations of paternal and maternal genes in any gamete.
What happens to the nucleus of spermatid during spermiogenesis?
During spermiogenesis, the nucleus of spermatid shrinks by losing much of its water from the nuclear cap and the chromosomes become closely packed into a small volume. Whole of ribonucleic acid is eliminated, leaving only the genetic material, the deoxyribonucleo protein.
When does spermatogenesis begin in the male body?
Spermatogenesis begins in male after puberty and it is continued throughout life. Even though sperms are continuously being formed in the testes, not all areas of the testes can form sperm at the same time.
