Chromosomes and Meiosis: Understanding Genetic Variation

This lecture covers the process of chromosomes duplicating, homologous chromosomes separating, and sister chromatids separating in meiosis. It also explains the different stages of meiosis, including metaphase, prophase, and spindle microtubule formation, as well as the consequences of nondisjunction in meiosis. The lecture concludes with the impact of nondisjunction on fertilization, leading to genetic variation.
