In guinea pigs, white coat (w) is recessive to black coat (W) and wavy hair (v) is recessive to straight hair (V). A breeder crosses a guinea pig that is homozygous for white coat and wavy hair with a guinea pig that is black with straight hair. The F1 are then crossed with guinea pigs having white coats and wavy hair in a series of testcrosses. The following progeny are produced from these testcrosses:

black, straight  -   220             black, wavy  -30

white, straight  -30                   white, wavy- 220

If the genes are not assorting independently, what is the distance between coat color and hair shape governing gene
