Confused on 2 questions here If a recombination frequency between two genes is 1.5%, what is the distance between the genes in map units on the linkage map? a. Impossible to determine, because the interference is not known. b. 1.5 c. 3 d. 0.75 Recombination frequencies a. arise from completely random genetic exchange. b. are the same for all genes. c. decrease with distance. d. are the same for cis and trans heterozygotes. I thought it was b for the first part a for the second part and but I'm wrong. Can someone explain?
