respectively, then how many chromosome and how much DNA will present during metaphase-
I and metaphase - II respectively?
(A) 40,400,20,200
(B)20,200,40,400
(C) 40,200, 40, 200
(D)20,400, 20,200​

Answer 2

Answer:

the correct answer is (A) 40, 400, 20, 200.

Explanation:

The number of chromosomes in meiosis-1 gets doubled and the number of chromosomes in meiosis-2 gets halved leaving the cell Haploid. Therefore, the number of chromosomes in metaphase-I is 40 and the number of chromosomes in metaphase-II is 20 resulting in the haploid gamete.

The number of DNA is to be equally divided into four daughter cells, so the DNA becomes 400 in metaphase-I and the quantity of DNA becomes 200 during metaphase-II resulting in 100pg DNA in all four daughter cells at the end of Meiosis-2.
