In gunea pigs , short har (L) is dominant to long hair (l) and heterozygous conditions of yellow coat (cy) and white coat (Cw) give cream coat. A short-haired, cream guinea pig is bred to a long-haired, white guinea pig, and a long haired , cream baby guinea pig is produced. when the baby grows up it is bred back to the short-haired, cream parent. what phenotypic classes and in what proportions are expected among the offspring?
