Reference no: EM1385786

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 female guinea pig that is homozygous for white coat and straight with a male guinea pig that is homozygous for both black and wavy hair. The F1 are then testcrossed a number of times and 44 guinea pigs were produced with the following phenotypes: 5 guinea pigs with black, straight hair; 16 guinea pigs with black, wavy hair; 17 guinea pigs with white, straight hair; and 6 guinea pigs with white wavy hair.
