In Drosophila flies, the allele b gives a black body, and the allele b+ gives brown, the wild-type phenotype. The allele wx of a separate gene gives waxy wings, and wx+ gives non-waxy. The allele cn of a third gene gives cinnabar eyes, and cn+ gives red. A female heterozygous for these three genes is testcrossed, and 745 progenies are produced which are phenotypically classified as follows: (see image) Make a linkage map of the three genes. Compute for interference and explain what the derived value means
