Black fur is considered dominant over yellow fur in Labrador Retrievers.

What is the probability of black fur in offspring of parents that are heterzygous for the trait?

In humans, curly hair is considered dominant over straight hair. If a heterozygous female mates with a male that is homozygous for straight hair, what is the probability that the offspring will be born with curly hair?

For a person to be left-handed, that is considered to be recessive to the more dominant trait for right-handedness.

What is the probability of an offspring being right-handed with the cross of a male that is homozygous for right handed to a female that is homozygous for left-handed?

In parrots, green feathers is dominant over blue feathers. If a parrot breeder wants to breed only blue parrots, what parental genotypes should they use? 

Albinism is an autosomal recessive condition. Which circle graph shows the genotype probability when an albino female mates with a male that is heterozygous for the albinism trait?

In cocker spaniels the allele for a black coat color (B) is dominant over the allele for a brown coat color (b).If a heterozygous cocker spaniel is crossed with a heterozygous black cocker spaniel, which of the following genotypic ratios can be expected?

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 straight feathers?

Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for this trait. If the stem characteristics are determined by a single gene, what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems?

In cats, solid fur color is considered dominant over spotted fur color. If a cat that has spotted fur is crossed with a cat that is heterozygous for fur color, what percentage of the offspring will be born with spotted fur?

Dogs can be born with a tail length of various sizes and it is possible that a single gene determines this trait. A dog with a long tail is considered to be the dominant trait over the recessive short tail trait.
