Document Summary
So it appears parental even though there were recombinations. Sco2 (single crossover region: smallest pair values: double-crossover, very rare, class the following data set by p,sco1,sco2 and dco (f2 data) q op c 1768 q+ op+ c+ 1701. ^^p q op+ c+ 263 q+ op c 271. ^^ sco1 q+ op c+ 140 q op+ c 128. ^^ dco: find the mapping distances for the following data. A-b: look identify values for recombinant genotypes of a-b (a/b+) or (a+/b). Ignoring c value: find them: a+ b c+ sco = 131 a+ b c sco = 252 a b+ c+ sco = 241 a b+ c sco = 118, sum them. = (recombinants / total) x 100 = 742/4197 = The odd one out is the middle gene. ^^ here the y"s are both wilde and m"s are both mutant, and the w"s differ. So w is the middle gene: determine, f1 genotype, gene order.
