guinea pigs, short hair (L) is dominant to long hair (l), and the heterozygous conditions of yellow coat (C Y ) and white coat (C W ) 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?

Question

In guinea pigs, short hair (L) is dominant to long hair (l), and the heterozygous conditions of
yellow coat (C
Y
) and white coat (C
W
) 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?
