In dogs, solid coat color (S ) is dominant over white spotted coat (s ). In a cross between two heterozygous dogs, what would be the probability of having a first litter of six pups, the firstborn with spotted fur, and then among the next five, three with solid fur and two with spotted fur; and then a second litter of seven pups in which the firstborn is spotted, the second born is solid, and then the remaining five pups are composed of three solid and two spotted animals.

In guinea pigs, black coat color is dominant over white, short hair is dominant over long, and rough coat is dominant over smooth.

In dogs, the allele for black coat color (B) is dominant to the allele for brown coat color (b). But if a dog has two copies of the recessive allele for a pigment-depositing gene (e), it can only have yellow coat color. In a cross of two doubly heterozygous black dogs (BbEe x BbEe), what fraction of the next generation would we expect to be yellow? WHY? a.1/8 b.1/4 c.2/3 d.3/16

In Triskelian cats, in the Blondish Galaxy, black coat color is dominant over grey. Coat color is determined by a single autosomal gene with two alleles: B = black coat color; b = grey coat color. The autosomal gene for eye color is hypothesized to assort independently from the gene for coat color. The two alleles are: R = green eye color; r = blue eye color. If a green-eyed black female cat whose mother has a grey coat and...

In a hypothetical breed of dogs, coat color is controlled by two genes. There are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. Consider the following crosses. Cross 1: Black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. F1 males and females are all black. When F1 are intercrossed, F2 males and females are black or brown. Cross 2: Black females from...

  Suppose that a particular gene that controls coat color in dogs is controlled by four alleles in the population. These alleles are called cch (chinchilla dog), cd (white dog with dark eyes), cb (pale gray dog) and c (albino dog). The alleles are given from the most dominant to the most recessive. Let’s assume that a particular population of these dogs is in Hardy-Weinberg equilibrium. The allele frequencies for our four alleles are: cch = 0.37 cd = 0.23 cb...
