WebAug 19, 2024 · No recombination or crossing over occur. Meiosis: The resulting daughter cells contain different combinations of genes. Genetic recombination occurs as a result of the random segregation of homologous chromosomes into different cells and by the process of crossing over (transfer of genes between homologous chromosomes). WebFertilization. Fertilization creates genetic diversity by allowing each parent to randomly contribute a unique set of genes to a zygote.
