Question

During which step of meiosis do the pairs of homologous chromosomes split up, but the sister chromatids stay attached?

A. anaphase I
B. anaphase II
C. metaphase I
D. metaphase II

Answer 1

A) Anaphase I

Step-by-step explanation:

During the Anaphase I of meiosis, the pairs of homologous chromosome split up. During this phase sister chromatids of each pair is formed and start moving towards the opposite poles. By the end of anaphase out of each pair of sister chromatids , reaches to the poles of the spindle fibre. During the metaphse of meiosis the chromosomes start their movements and arrange themselves between the poles and the equator of the spindle.
