Mendel’s law of independent assortment explains how different traits are inherited by stating that the alleles of a gene pair located on one pair of chromosomes are inherited independently of the alleles of a gene pair located on a different chromosome pair.1

During meiosis, homologous chromosomes—one of maternal origin and one of paternal origin—separate and are distributed into sex cells. Because these different pairs of chromosomes assort independently, the genes they carry are also shuffled into new combinations. This process ensures that offspring receive a unique mix of genetic material from their parents, contributing to the genetic variety observed within a species.2

It is important to note that this principle applies specifically to genes located on different chromosomes. Genes located on the same chromosome are part of a linkage group and tend to be inherited together, meaning they do not always comply with the law of independent assortment unless separated by crossing over.32
