Exercise 4

Following up on the observations in Question 10, you complete new crosses using gene O. You observe 30% recombination for a cross between MO and mo , 35% recombination for a cross between LO and lo , and 25% recombination for a cross between NO and no. Assume all crosses are between diploid flies homozygous for the alleles of these genes. Given the information from Questions 10 and 11, draw a map placing the genes in the proper order and give the distance between each gene in map units.
