In pigs, the dominant C allele produces a curly tail. c/c homozygotes have straight tails. The recessive w allele produces white hair, whereas the W allele produces brown hair. The C and W genes (loci) are on the same chromosome.    A    C W / c w heterozygote (curly, brown) is test crossed to a c w / c w (straight, white) homozygote multiple times. They produce a total of 100 progeny, of which 20 have curly tails and white hair. What is the distance between the C and W loci, in map units?   A.10 B. 20 C. 30 D.40
