The spermatogonial cell has 46 chromosomes in human male. Give the number of chromosomes in -
(A) primary spermatocyte
(B) Spermatids
Dear Student,
If the Spermatogonial cell has 46 chromosomes in human male , then the number of chromosomes found in
a) primary Spermatocyte would be 46
This is because , as Spermatogonium is Diploid (2n Chromosome) undergoes Mitosis and form a Primary Spermatocyte which is also Diploid in number (2n). So the chromosome number would remain the same.
and ,
b) In Spermatids , it would be 23.
This is because Primary Spermatocytes undergoes Meiosis I to form Secondary Spermatocyte which in turn form FOUR Spermatids by Meiosis II which are Haploid in Number (n). So the chromosome number will reduce by half.
Regards
