Question

The amount of DNA in a mammalian cell in early prophase I is x.
What is the amount of DNA in the same cell in anaphase I of meiosis?

• A. $\frac{x}{4}$
• B. $\frac{x}{2}$
• C. x
• D. $2x$

Answer 1

Answer: (A)

$\frac{x}{4}$

Meiosis I begins with diploid (2n=4) cell and ends with two haploids (n = 2) cells. In humans ( 2n=46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis. I (n=23).

So, the correct option is 'x/4'.
