Question

6. You have conducted exhaustive experiments studying the inheritance of four genes (A, B, C, and D) that are all on chromosome 3 in Drosophila melanogaster. You have recorded the following frequencies of recombination in offspring for each of the genes: Gene pair: Frequency of Recombination: a b 20 a c 28 a d 5 b c 10 b d 15 c d 24 1. What is the order of the genes on the chromosome? 2. Why is the distance between genes a and c as shown in the data?
