The nuclear DNA content of a single sperm cell in Drosophila melanogaster is approximately 0.18 picogram. What would be the expected nuclear DNA content of a primary spermatocyte in Drosophila

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,

0.18*4 = DNA content of primary spermatocyte

DNA content of primary spermatocyte = 0.72 picogram
