Homologous c hromos omes s eparate in both meios is I and meios is II. ANSWER: Correct Meios is inv olv es two s equential c ellular div is ions . In meios is I, homologous c hromos omes pair and then s eparate. Thus , although the parent c ell is diploid (c ontaining two c hromos ome s ets , one maternal and one paternal), eac h of the two daughter c ells is haploid (c ontaining only a s ingle c hromos ome s et). In meios is II, the s is ter c hromatids s eparate. The four daughter c ells that res ult are haploid.
