Question

a. how does anaphase i in meiosis differ from anaphase in mitosis?

Explanation:

To answer this, we analyze the processes: In mitotic anaphase, sister chromatids separate and move to opposite poles. In meiosis anaphase I, homologous chromosomes separate (sister chromatids remain attached). This difference relates to the goals of meiosis (producing haploid cells with genetic variation) vs mitosis (producing identical diploid cells).

Answer:

In anaphase of mitosis, sister chromatids separate and move to opposite poles. In anaphase I of meiosis, homologous chromosome pairs separate (sister chromatids of each chromosome remain attached at the centromere and move together to the same pole).
