Describe independent assortment and why it is the main source of genetic variability in meiosis

Independent assortment can be described as the phenomenon through which genes and chromosomes assort independently into gametes, during the process of meiosis. The alleles of a gene assort independently into chromosomes. Due to this phenomenon, variations are produced among parents and offsprings. For example, parents who are carriers of disease can transfer both the disease-causing alleles in offsprings. Due to this, the offspring will have the disease whereas the parents would be normal.
