Question

Which of these is true about anaphase I?

(a) Sister chromatids remain attached at the centromeres

(b) Bivalent is unequally separated

(c) Homologous chromosomes remain together

(d) It takes place before diakinesis

This question was posed to me at a job interview.

My question is taken from Cell Cycle and Division in chapter Cell Cycle and Cell Division of Biology – Class 11

Answer 1

Correct option is (a) Sister chromatids remain attached at the centromeres

To explain: During anaphase I of meiosis, the homologous chromosomes are separated and the bivalent is hence, equally divided. It takes place after diakinesis, which is a part of prophase I. Sister chromatids are not separated.
