Question

How do cells at the completion of meiosis compare with cells that are in prophase of meiosis I? They have _____.

A) half the number of chromosomes and half the amount of DNA.
B) the same number of chromosomes and half the amount of DNA.
C) half the number of chromosomes and one-fourth the amount of DNA.
D) half the amount of cytoplasm and twice the amount of DNA.

Answer 1

During meiosis, cells in prophase I have the same number of chromosomes as the parent cell, while cells at the completion of meiosis have half the number of chromosomes.

Step-by-step explanation:

Cells in prophase of meiosis I have the same number of chromosomes as the parent cell, but with each chromosome consisting of two sister chromatids due to DNA replication.

On the other hand, cells at the completion of meiosis have half the number of chromosomes as the parent cell, as a result of chromosome separation during anaphase I and anaphase II.

So, the correct answer is A) half the number of chromosomes and half the amount of DNA.
