Identify the meiotic stage in which the homologous chromosomes separate while the sister chromatids remain associated at their centromeres?

Options

(a) Metaphase – I
(b) Metaphase – II
(c) Anaphase – I
(d) Anaphase – II

Correct Answer:

Anaphase – I

Explanation:

Anaphase I begins when the two chromosomes of each bivalent (tetrad) separate and stat moving toward opposite poles of the cell as a result of the action of the spindle. In anaphase I the sister chromatids remain attached at their centromeres and move together toward the poles.
