Identify the meiotic stage in which the homologous chromosomes separate

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.
