Question

meiosis: number of chromosomes at the end of meiosis ii
if a cell contains 12 chromosomes at the end of meiosis i, how many chromosomes will the daughter cells contain at the end of meiosis ii?
multiple choice
3
24
12
6

Explanation:

Step1: Understand meiosis I and II

Meiosis I reduces chromosome number by half. But meiosis II is similar to mitosis. It separates sister chromatids.

Step2: Analyze chromosome number change

At the end of meiosis I, the cell has 12 chromosomes. During meiosis II, sister chromatids separate. But the number of chromosomes (each chromatid becomes a chromosome) remains the same as at the start of meiosis II for each daughter cell. So each daughter cell at the end of meiosis II has 12 chromosomes.

Answer:

12
