The non-wild-type alleles are k (clipped wings), l (long tail), and m (magical powers). The parental stocks are homozygous doubly recessive flies of genotype k+/k+ · l/l · m/m and homozygous singly recessive flies of genotype k/k · l+/l+ · m+/m+. From this cross, triply heterozygous progeny of genotype k/k+ · l/l+ · m/m+ are obtained, and females of this genotype are testcrossed to triple recessives of genotype k/k · l/l · m/m. The genotypes determining the eight progeny types from this testcross (CROSS C) are shown here with their numbers, out of a total sample of 1,572 flies. What is the correct order of the genes? What number of progeny for each genotype would you predict in the case of independent assortment? What is a non-recombinant genotype? What is a genotype of a single crossover? What is a genotype of a double crossover? What is the longest distance between any of the two dragon alleles above? What is the shortest distance between any of the two dragon alleles above? What is NOT a distance between any of the two dragon alleles above? What is the coefficient of coincidence for the dragon alleles above? What is the interference for the dragon alleles above?
