Question

1 multiple choice 1 point in anaphase i _ separate, and in anaphase ii _ separate. chromosomes; haploid cells haploid cells; diploid cells chromatids; homologous chromosomes homologous chromosomes; chromatids

Explanation:

In meiosis, during anaphase I, homologous chromosomes separate. This is because meiosis I is the reduction - division stage where the diploid number of chromosomes is halved. In anaphase II, sister chromatids separate. This is similar to mitosis, but the starting material in anaphase II is haploid cells (from the end of meiosis I).

• Option 1: Chromosomes separating in anaphase I is incorrect as it's homologous chromosomes. Haploid cells do not separate in anaphase II.
• Option 2: Haploid and diploid cells do not separate in these phases.
• Option 3: Chromatids do not separate in anaphase I and homologous chromosomes do not separate in anaphase II.

Answer:

homologous chromosomes; chromatids (the fourth option)
