Answer:
The correct answer is - 0.72 pg.
Explanation:
A we know that, genetic material present in one primary spermatocyte divides in between four sperm cells that means that each sperm cell has 25 percent of DNA or genetic material of the primary spermatocyte.
Given:
1 sperm cell = 0.18 nuclear DNA
So,[tex]DNA content of one sperm cell = \frac{\text DNA content of primary spermatocyte}{4}[/tex]
0.18*4 = DNA content of primary spermatocyte
DNA content of primary spermatocyte = 0.72 picogram
