WebConsider three genes on the same chromosome, geneD, geneE and geneF. To determine the distance between and order of these three genes, you conduct a test cross between a heterozygote DEF / def and a def / def homozygous recessive. The offspring produced from the cross are shown in the table. What is the distance between the genes? WebGenetic linkage occurs when the genes controlling two different traits are located near each other on the same chromosome . The basic idea is that if two genes are on the same chromosome, and you inherit the whole chromosome, then you have to inherit those two genes (and whatever alleles they have) together.
