Disjunction of homologous chromosomes occur in
Answers
Answer:
Disjunction normally occurs during the anaphase of mitosis and meiosis (I and II). ... In meiosis, disjunction happens when homologous chromosomes move apart toward the opposite poles of the cell in anaphase I. Disjunction again occurs when sister chromatids separate and move away from each other during anaphase

Answer:
in Anaphase of mitosis
and Anaphase 1 and Anaphase 2 of meiosis
Explanation:
In Anaphase of mitosis the chromosomes which was aligned at the metaphase plate or in one line they move towards opposite poles. Centromere splits and sister chromatid starts moving towards opposite pole with their arms towards center and centromere towards poles.
In ANAPHASE 1 of meiosis the bivalent ( 2 homologous chromosome that are attached to each other by synaptonemal complex )start moving towards opposite poles. Therefore in this Anaphase 1 homologous chromosome move towards opposite poles without splitting of centromere.
In Anaphase 2 of meiosis the homologous chromosome breaks by their centromere and now sister chromatids start moving towards opposite poles with their arms towards center and centromere towards poles
