sister chromatids separate in Anaphase I and homologous chromosomes separate in Anaphase II
|
Detailed explanation-1: -The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.
Detailed explanation-2: -Another difference is that in anaphase 1, the spindle fibres are joined to the centromere of the chromosomes, which belong to two different sets. In contrast, in anaphase 2, the spindle fibres are joined to the single chromosome containing two sister chromatids through one centromere.
Detailed explanation-3: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
Detailed explanation-4: -The cleavage of the centromere is taken place in Anaphase of Mitosis, whereas it does not occur in Anaphase I of meiosis.
Detailed explanation-5: -During anaphase I, the homologous chromosome pairs separate and are pulled to opposite poles of the cell by spindle fibers attached to the centrioles. This first cell division process is completed during telophase I.
