Detailed explanation-1: -It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other. This called is called independent assortment.

Detailed explanation-2: -What is the Difference Between Random Orientation and Independent Assortment? Random orientation is the random line up of homologous chromosome pairs at the cell equator while the independent assortment is the inheritance of genes independently from the inheritance of any other gene.

Detailed explanation-3: -Independent assortment is random and occurs during Metaphase I of meiosis. There are two possible alignments for the chromosomes. Since the alignments are random and not assigned, genetic variation occurs.

Detailed explanation-4: -Independent assortment produces new combinations of alleles. In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis.

Detailed explanation-5: -The physical basis for the law of independent assortment lies in meiosis I of gamete formation, when homologous pairs line up in random orientations at the middle of the cell as they prepare to separate.
