In cattle, coat color is inherited in a co-dominant fashion. Homozygous C R C R produces red coat,homozygous C W C W produces white coat, and the heterozygous C R C W produces roan-colored coat.What is the probability of having a roan-coated offspring in a cross between a white-coated cattle anda roan-coated cattle?
In the fictitious monster Lochnessius coolnameii, coat color is under the control of an autosomal gene, with white coat (W) dominant over black coat (w). The monster’s ability to produce horns is a sex-influenced trait, that is dominant in males but recessive in females. Let Horned = H, and hornless = h. Consider the cross of a homozygous white & horned male with a homozygous black & hornless female. What genotypes and phenotypes are expected in the F1? What genotypes and phenotypes are expected in the F2? In what ratios? Zappy is a horned white male. It was bred to the following four females, and the results are presented here: Mother Offspring Alcremie: hornless, black 1 horned white female Blissey: hornless, white 1 hornless black female Chansey: horned, black 1 horned, white female Delcattie: hornless, white 1 hornless, black male + 1 Horned white…
Farmer Brown had two hogs, Olga and Hank. Olga and Hank were normal, healthy hogs, but whenever Farmer Brown crossed them, a few of the piglets had cleft palates. Assuming a simple autosomal basis for cleft palate, what are the genotypes of Olga and Hank, and about what proportion of the piglets are born with a cleft palate?

In chickens, the Leghorn variety has white feathers due to an autosomal dominant allele. Silkies have white feathers due to a recessive allele in a second (different) gene. If a true-breeding whiteLeghorn is crossed to a true-breeding white Silkie, what is theexpected phenotype of the F1 generation? If members of the F1generation are mated to each other, what is the expected phenotypic ratio of the F2 generation? Assume the chickens in the parental generation are homozygous for the white allele at one gene andhomozygous for the brown allele at the other gene. In subsequentgenerations, nonwhite birds will be brown.
In guinea pigs, the gene for black coat color is dominant to the gene for white coat color. What will be the genotypic ratio for the cross between two heterozygous parents?
