WebJan 1, 2024 · This is the process of independent assortment. Thus, this is the summary of the difference between random orientation and independent assortment. Both these events lead to the unique composition of alleles or genes in the gametes at the end of the meiosis. Reference: 1. “7.6: Genetic Variation.” WebMar 6, 2024 · It is the specific processes of meiosis, resulting in four unique haploid cells, that result in these many combinations. This independent assortment, in which the chromosome inherited from either the father or mother can sort into any gamete, produces the potential for tremendous genetic variation.

How Meiosis & Fertilization Promote Genetic Variation

WebGenetic variation occurs during meiosis I, in which homologous chromosomes pair and exchange non-sister chromatid segments (crossover).
