Question

At which stage of meiosis are homologous chromosomes separated, affecting genetic composition?
Options
A Telophase II – chromosomes recombine
B Anaphase I – reduces chromosome number, contributing to genetic variability
Correct Answer
C Prophase I – duplicates DNA
D Metaphase II – aligns sister chromatids for division
Correct Answer

Option B is the correct answer.

Detailed Explanation

During anaphase I, homologous chromosomes are pulled to opposite poles. This reduces the chromosome number and, combined with independent assortment, contributes to genetic diversity.

Hint

Separation of homologous pairs, not sister chromatids, defines this phase.
