In Labrador retriever dogs, the allele for a black-coloured coat (B) is dominant to the allele for a chocolate-coloured coat (b). And the allele for a curly tail (C) is dominant to the allele for a straight tail (c). Suppose a male dog that is heterozygous for both coat colour and tail is mated with a female dog that is homozygous dominant for coat colour but homozygous recessive for a straight tail.

In mice, the presence of a dominant A allele results in the agouti pattern of fur color, whereas the aa homozygous recessive results in a solid color pattern. The presence of another dominant B allele results in black fur color, whereas the homozygous recessive bb results in brown fur color. The presence of a third dominant C allele is required for any color to be observed (brown or black), whereas the homozygous recessive cc results in lack of any color whatsoever (albino). What is the phenotype of a mouse with the following genotype? Aa bb cc albino Agouti color pattern and brown Solid color pattern and brown Agouti color pattern and black Solid color pattern and black
In rabbits, black hair is dependent on a dominant allele B, and brown upon arecessive allele b. Short-hair is due to dominant allele S and long hair to arecessive allele s. If a true-breeding black short haired male is mated with abrown, long-haired female, what will their offspring look like? What will be the genotypes of the offspring?
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?
In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
In rabbits, black hair depends on a dominant allele, B, and brown hair on a recessive allele, b. short hair is due to a dominant allele, S, and long hair to a recessive allele, s. If a true-breeding black short-haired male is mated with a brown long-haired female, describe their offspring. What will be the genotypes of the offspring? If two of these f1 rabbits are mated, what phenotypes would you expect among their offspring? In what proportions?
In cats, white patches are caused by the dominant allele P, while pp individuals are solid-colored. Short hair is caused by a dominant allele S, while ss cats have long hair. A long-haired cat with patches whose mother was solid-colored and short-haired mates with a short-haired, solid-colored cat whose mother was long-haired and solid-colored. What kinds of kittens can arise from this mating, and in what proportions? Show your solution. Explain your answers.
In rural northeast Kansas domesticated cats are becoming wild, and biologists are observing that wildcats occur in three colors. Fur color is controlled by a single gene that exhibits incomplete dominance. A homozygous dominant cat is blue (BB), a homozygous recessive cat is red (bb), and a heterozygous wildcat will be purple (Bb). What would be the expected phenotypes of the offspring if a blue wildcat mates with a red wildcat? Develop a Punnett square and list the genotypes as well.
Within a mouse population, the black fur allele (B) is dominant to the white fur allele (b) and the short whisker allele (S) is dominant to the long-whisker allele (s). A heterozygous black-furred short-whiskered mouse is crossed with a homozygous white-furred long-whiskered mouse. What percentage of the offspring will be black-furred with long whiskers?
In a species of dog, plaid color is represented by P and purple by p, short -tailed is T and long-tailed is t. What are the genotypes of a male who is purple with a long tail, and a female who is homozygous dominant for both traits? Which answer below is true? PpTT & PPTT pptt & PPTT short-tailed purple & long tailed plaid male: purple w/ long tail & female: plaid w/ short tail
You find a population of 200 mice in which 32 of them display the recessive fur color. What is the genetic structure (the allelic and genotypic frequencies) in that population, with respect to fur color?
. In tigers, a recessive allele of a particular gene causes both anabsence of fur pigmentation (a white tiger) and a cross-eyed condition. If two phenotypically normal tigers that are heterozygousat this locus are mated, what percentage of their offspring will becross-eyed? What percentage of cross-eyed tigers will be white?
In cocker spaniels, solid coat color is dominant over spotted coatcolor. If two heterozygous dogs were crossed to each other, whatwould be the probability of the following combinations of offspring?A. A litter of five pups, four with solid fur and one with spotted fur.B. A first litter of six pups, four with solid fur and two with spotted fur, and then a second litter of five pups, all with solid fur.C. A first litter of five pups, the firstborn with solid fur, and thenamong the next four, three with solid fur and one with spottedfur, and then a second litter of seven pups in which the firstborn is spotted, the second born is spotted, and the remainingfive are composed of four solid and one spotted animal.D.
