Web11 de mar. de 2024 · Once the frequency of recombination is known for each pair of genes, the geneticist can construct a linkage map that shows the order and relative distances between genes on a chromosome. The unit of distance on a linkage map is called a centimorgan (cM), which represents 1% recombination between two genes. WebExercise 4.5.1. 3. Consider 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.
