Homologous chromosomes move toward opposite poles of a dividing cell during which phase of meiosis?
A
Telophase II
B
Metaphase I
C
Anaphase I
D
Anaphase II
Verified step by step guidance1
Recall that meiosis consists of two sequential divisions: meiosis I and meiosis II, each with distinct phases (prophase, metaphase, anaphase, telophase).
Understand that homologous chromosomes are pairs of chromosomes (one from each parent) that pair up during meiosis I, while sister chromatids are duplicated copies of a single chromosome.
Identify that the movement of homologous chromosomes toward opposite poles occurs during anaphase I, where the homologous pairs are separated.
Contrast this with anaphase II, where sister chromatids (not homologous chromosomes) are pulled apart toward opposite poles.
Therefore, the phase in which homologous chromosomes move toward opposite poles is anaphase I.
