Chromosomes from each homologous pair are randomly sorted into daughter cells in a process called independent assortment. This gives them a greater amount of genetic diversity.
When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells after which different chromosomes segregate independently of each other. This is known as independent assortment. It leads to the formation of gametes that have unique combinations of chromosomes.
In humans, there are more than 8 million configurations in which the chromosomes can line up during metaphase I of meiosis. This process of meiosis creates four unique haploid cells which lead to these numerous combinations.
