Question

Quizplus · Accepted Answer

Meiosis II is not involved in generating genetic variation. Meiosis I, crossing over, and independent assortment all contribute to genetic variability through various mechanisms. Meiosis I separates homologous chromosomes, randomly distributing paternal and maternal chromosomes to daughter cells, while crossing over involves the exchange of genetic material between homologous chromosomes. Independent assortment also leads to a random distribution of maternal and paternal chromosomes to daughter cells. Meiosis II then separates sister chromatids, resulting in the production of haploid gametes with unique combinations of genetic material.
