Assuming no crossing over between the gene in question and the centromere, during what phase of meiosis do alleles segregate?
choli [55]

Answer:

During Anaphase stage

Explanation:

Meiosis is the type of cell division employed during gamete formation when each resulting gamete (daughter cell) has their chromosomal number reduced by half. Meiosis occurs in a two step division; Meiosis I and II. Meiosis I involves the separation of homologous chromosomes (similar but non-identical chromosomes received from each parent) while Meiosis II involves separation of sister chromatids (replicated chromosomes).

Alleles are present on the chromosomes which segregate or separate during the anaphase stage. Alleles received from each parent are separated in Anaphase I of meiosis I, which the identical replicated alleles are separated in anaphase of meiosis II.
