In cats, white patches are caused by the dominant allele P while p/p individuals are solid colored. Short hair is caused by the dominant allele S, while s/s cats have long hair. A longhaired cat with patches whose mother was solid-colored and shorthaired mates with a shorthaired, solid-colored cat whose mother was longhaired and solid-colored. What kinds of kittens can arise from this mating and in what proportions? Outline the cross and assign genotypes, phenotypes, and proportions in the space below.

F1 progeny:

In man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a marriage between a heterozygous spotted, non-wooly man with a heterozygous wooly-haired, non-spotted woman. Give genotypic and phenotypic ratios of offspring.
In horses, black is dependent upon a dominant gene, B, and chestnut upon its recessive allele, b. The trotting gait is due to a dominant gene, T, the pacing gait to its recessive allele, t. If a homozygous black pacer is mated to a homozygous chestnut trotter, what will be the appearance of the F1 generation?
In hamsters, black fur (B) is dominant over brown fur (b) and long fur (L) is dominant over short fur (l). A black, long furred female whose mother had brown fur and whose father had short fur is mated with a black, short furred male whose father had brown, long fur.
What is the probability that the first three offspring will have brown, long fur?
What is the probability that the first offspring will have black, long fur?
What is the probability that one of the first three offspring will have black, long fur and the other two brown, short fur?

- In Labrador dogs, coat color is controlled by the genotypes of two genes. In one gene, the dominant allele, B, produces black fur, and the recessive allele, b, produces brown fur. However, if a second gene possesses two recessive alleles, ee, the dog produces yellow fur, regardless of the genotype of the first gene. If two dogs that are heterozygous for both genes, BbEe mated, what would be the frequency of the three phenotypes, black, brown, and yellow?arrow_forwardIn cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black?
