In order to map the distance between two linked genes, CC DD individuals were crossed to cc dd individuals. The F1 generation was then testcrossed to cc dd individuals. The resulting individuals had the following genotypes: 903 individuals with the genotype Cc Dd 897 individuals with the genotype cc dd 98 individuals with the genotype Cc dd 102 individuals with the genotype cc Dd (A) How far apart are the c and d genes? Show your work. Explain how to do it? I get that it’s 98+102 because those two are recombinant DNAs (lowest number) divide by (903+897+98+102) = 0.10 so 10 map units but how do you get distance between Cd and CD and cd and cD?
