Difference between anaphase and anaphase 1
WebMay 24, 2024 · Failure of homologous chromosomes to separate towards the poles during anaphase 1 is known as nondisjunction in meiosis 1. Failure of sister chromatids to separate towards the poles during anaphase 2 in meiosis is known as nondisjunction in meiosis 2. Homologous chromosomes fail to separate properly in meiosis I. WebThe chromosomes can be seen clearly during metaphase. The sister chromatids of each chromosome are linked at the centromere, but their arms remain free. Anaphase Anaphase is the third stage of mitosis. The chromatids split at the centromere during anaphase. This begins to travel towards the poles.
