Question

what is the overall purpose of meiosis?
multiple choice
to produce four genetically identical haploid cells
to produce four genetically different diploid cells
to produce four genetically different haploid cells
to produce four genetically identical diploid cells

Explanation:

Meiosis is a type of cell division that reduces the chromosome number by half. It involves two rounds of division (meiosis I and meiosis II). During meiosis I, homologous chromosomes pair up, exchange genetic material (crossing - over), and then separate. This leads to genetic variation. After meiosis I, the cells are haploid (half the chromosome number of the original diploid cell). In meiosis II, sister chromatids separate. The end result is four non - identical (due to crossing - over and independent assortment in meiosis I) haploid cells. Mitosis, on the other hand, produces genetically identical diploid cells. So, the purpose of meiosis is to produce four genetically different haploid cells.

Answer:

to produce four genetically different haploid cells
