The anaphase 1 shows which of the following?(a) Chromatids separate to one pole(b) Centromere is 1st to separate(c) The chromosomes separate to 4 cells(d) Each homologue reaches opposite poleI got this question during an internship interview.This question is from Meiosis 1 Metaphase, Anaphase & Telophase topic in division Chromosomal Changes During Meiosis of Cytogenetics

Answer»

Right OPTION is (d) Each homologue reaches opposite pole

The BEST EXPLANATION: In anaphase 1 it is true that the homologous move to opposite pole. The result of meiosis is ultimately 4 cells but not by 1 division. The chromatids don’t separate; centromere still binds the chromatids rather the chromosome separates at the CHIASMA interactions.
