You again want to map the positions of three genes (l, m, and n) in drosophila. each gene has one dominant allele and one recessive allele. you perform the three different two-fac- tor crosses (cross 1: lm and lm, cross 2: mn and mn, and cross 3: ln and ln). assume all crosses are between diploid flies homozy- gous for the alleles of these genes. you observe 5% recombinants in the first cross, 50% recombinants in the second cross, and 50% recombinants in the third cross. based on the data given, what can you determine for the gene order and distance between the genes?
