Final answer:
Linked genes on the homologous chromosomes show up in different gametes less than 50 percent of the time and are assumed to be on the same chromosome.
Step-by-step explanation:
When two genes are located in close proximity on the same chromosome, they are considered linked, and their alleles tend to be transmitted through meiosis together. For linked genes, the segregation of alleles on the homologous chromosomes is critical. These linked genes show up in different gametes less than 50 percent of the time and are assumed to be on the same (homologous) chromosome.
