10. Which of the following statements best describes the major difference between anaphase of mitosis and anaphase I of meiosis? (2pts)

a) In anaphase I, homologous pairs are separated but sister chromatids stay joined together.

b) In anaphase, spindle fibers pull each set of sister chromatids to opposite ends of the cell.

c) In anaphase I, sister chromatids are separated, forming a total of four haploid cells.

d) In anaphase, tetrads of homologous pairs are separated to form four new nuclei.

The answer will be A because mitosis usually separate the sister chromatids to sister chromosomes to form two diploid cells. In meiosis, the goal is to have four haploid cells. To form that, cells need to undergo cell division two times. In the case of meiosis I, sister chromatids stay joined together until it reaches meiosis II. Then, the sister chromatids will separate starting at anaphase II in meiosis II. For example, if you start with 92 chromosomes (46 chromatids) during meiosis I, at meiosis II you will have two cells with 46 chromosomes (23 chromatids). By the end of meiosis II, you should form 4 haploid cells that contains 23 chromosomes.
