Question

Assume 2n=12 in a hypothetical species. In gametogenesis, the number of chromosomes in a spermatid would be ____ and in a 1st polar body would be ____.
a) 3,6
b) 3,3
c) 6,3
d) 6,6​

Answer 1

Answer:

d )6, 6

is acorrect answer

Answer 2

Answer

The correct answer is d) 6,6

Explanation

Sperms and ovum (polar body) are formed by the gametogenesis process that takes place in the testis and ovary of male and female reproductive organs respectively.

These are the gametic cells which show meiotic division and lead to a decrease in the number of chromosomes by half. that mean if a somatic(diploid) cell carry 12 chromosomes that mean a gametic cell carry 6 chromosome which is a haploid cell.

These gametic cell takes part in the fertilization process and fuse and produces the diploid cell and regain the diploid state.

if a cell carries 12 chromosomes then its gametes cell carries 6 chromosomes in it, either its polar body or spermatid.

hence the answer is d
