Parents of genotypes AABBCC and aabbcc (all loci are linked) are crossed to produce F1. An F1 individual is test crossed to produce the following F2 phenotypes: abc, 244; AbC, 93; ABc 156; aBC, 5; abC 151; ABC, 250; Abc, 6; aBc, 95. What was the genotype (including gene order) of the F1 individual?
What is a map distance from B to C?
