In cattle the allele for cloven hooves (H) is dominant over the allele for mule-foot hooves (h). The phenotypes for each trait are shown below in the picture.

The probability (% chance) that the offspring will have cloven hooves if both parents are heterozygous is?

Chickens can have different types of feathers. Frizzled feathers curl toward a chicken’s head.

Assume that feather type is determined by a single gene and that the allele for frizzled feathers is dominant over the allele for straight feathers.

In a cross between two chickens with straight feathers, what percentage of the offspring can be expected to have frizzled feathers?
