The characteristics considered by Mendel and treated so far have involved genes that segregated independently from each other. However, consider the fact that if two genes are located on the same chromosome, then they are structurally linked and although the genes in question will always separate from their respective alleles and assort independently with other non-homologous chromosomes, the genes on the same chromosome usually stay together. Thus, consider   the hypothetical individual at the right with a single pair of chromosomes with two genes, A and B. Both genes are heterozygous with A and b linked on one chromosome and  a and B on the other. The gametes formed by this individual will have the following composition. Flip to the next card.
