Gene mapping is the process of determining the location of genes on chromosomes. Recombination between linked genes can be used to map their distance apart on the chromosome. What is the distance between the two genes if 15% of the gametes produced by meiosis are recombinant?

• Mapping reveals the relative order of genes, not the actual physical distance. • The most accurate maps are made by summing the genetic distances of genes lying close together (small intervals). One needs to connect genes that lie far apart through the genes that lie between them.

Calculate the map distance between loci given the phenotypes of offspring or predict phenotypes of offspring given the recombination frequency between loci. Use the distance to construct genetic maps based on data from two-point or three-point testcrosses.

Practice Problems for Genetics, Session 2: Linkage and Recombination, Genetic Maps Question 1 You are doing a genetics experiment with the fruit fly. In the “P” generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1
