Question

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 pole

I 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 1

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.
