Meiosis consists of two nuclear divisions (meiosis I and meiosis II) that reduce the number of chromosomes to the haploid number in preparation for sexual reproduction. Although the nucleus divides twice during meiosis, DNA replicates once. The products of meiosis are different from each other as well as from the parent cell. In particular, the functions of meiosis are:
1. Reduce the number of chromosomes from a diploid number to a haploid number.
2. Ensuring that each of the haploid products has one set of chromosomes.
3. Promote genetic diversity in its products. This is because the differences between haploid nuclei result from crossing over during prophase I and random segregation of homologous chromosomes during anaphase I.
The result of meiosis is 4 haploid nuclei (cells).
We can conclude that the correct answer is:
Answer:B. consists of two sets of divisions and produces four haploid daughter cells that are not identical.
