Solution
The correct option is C Anaphase of first meiotic division Anaphase I (anaphase of first meiotic division) begins when the two chromosomes (paired genes) of each bivalent (tetrad) separate and start 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.
