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?
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?
The correct option is C 12
The process of reduction division or meiosis is divided into two stages - meiosis I and meiosis II. In meiosis I, the daughter cells have half the number of chromosomes as compared to the parent cell. This division is followed by meiosis II which is identical to mitosis. In this process, each of the haploid daughter cells undergoes division to form two haploid cells. Overall, meiosis results in the formation of four haploid cells from a diploid parent cell. So if a cell has 12 chromosomes at the end of meiosis I which is reduction division, it means that the parent cell would have had 24 chromosomes in prophase I. At the end of meiosis II (which is similar to mitosis and hence, equational division occurs) it would have 12 chromosomes.
