Meiosis (3 of 3): Determinants of Heredity and Genetic Variation (BioFlix tutori

Part A - Independent assortment and genetic variation
Consider a diploid cell where 2n = 6. During metaphase I of meiosis, as the pairs of homologous chromosomes line up on the metaphase plate, each pair may orient with its maternal or paternal homolog closer to a given pole. There are four equally probable arrangements of the homologous pairs at metaphase I. (Note that this pr
