Summary Introduction
To explain:
The type of offspring formed when a black short-haired male rabbit is mated with a brown long haired female rabbit, genotypes of the offspring formed, and the
Introduction:
The rabbits have genes for long hair, short hair, black color and brown color of the body which forms a dihybrid cross. The crosses between these mice lead to the formation of the offspring.

In cats, the allele for black fur (B) is dominant over the allele for brown fur (b). A heterozygous female cat mated with a homozygous recessive male cat.a. What is the genotype of the female cat?b. What is the phenotype of the female cat?e. Draw a Punnett square to show what kinds of kittens these two cats could make. What fraction of the kittens would you expect to have each genotype?
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 certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes. All of their offspring (both female and male) had red eyes.a. Which is dominant, the allele for red eyesor the allele for white eyes?b. What is the genotype of the white-eyed parents?c. If the white-eyed parent was mated with one of the red-eyed offspring, what phenotypic ratio wouldyou expect regarding eye color?

- In guinea pigs, short hair (S) is dominant to long (s). Black fur (B) is dominant to albino (b). A female from a strain which is pure breeding for black fur and short hair is mated to a male from a strain pure breeding for the albino condition and long hair. (A). What will be the phenotypes of the F1? (B) If members of the F1 are mated among themselves, what percentage of offspring can be expected to be homozygous for both traits? Give the genotypes and phenotypes of these homozygotes.arrow_forwardIn cats, the allele (B) produces black color but (b) produces a yellow color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoiseshell color. The alleles (B) and (b) are sex-linked as well Cross a tortoiseshell female with a yellow male. a. What percent of their offspring will be yellow? b.What percent of their offspring will be black? c.What percent of their offspring will be tortoiseshell? d.Why is it impossible to have a tortoiseshell male offspring?arrow_forwardIn 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.arrow_forward
- Two alleles of gene C control hair color in horses: C¹and C². Horses homozygous for allele C¹ are red, heterozygotes are yellow, and C² homozygotes are cream. In the offspring of matings between heterozygotes, what phenotypic ratio is expected? A) 2 yellow: 1 red B) 3 red: 1 cream C) 1 red: 2 yellow: 1 cream D) all red E) 9 red: 3 yellow: 4 creamarrow_forwardIn 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 blackarrow_forwardIn cats, black fur (B) is dominant over brown fur (b). Also, striped fur (A) is dominant over solid colored fur (a). What is the phenotype of a cat with the genotype Bbaa? What combinations of gametes could the Bbaa cat make? If the Bbaa cat mated with a cat that was heterozygous for both the color and pattern genes, what fraction of their kittens would be likely to have solid brown fur?

- In gerbils, the gene that specifies coat color is sex‑linked and has multiple alleles, as follows: B ‑ black, br ‑ brown, by ‑ yellow, and b ‑ albino. The allele br is incompletely dominant over by, the combination br by giving tan color; otherwise, dominance is in the order given ‑‑ B, br, by, b. (For your information, gerbils are mammals.) A black gerbil mated with a yellow gerbil gave one brown male and one black female offspring. A. What is the sex of the black parent? b. What is the genotype of the brown offspring? c. If the two offspring were to mate with each other, what is the probability that they will have a yellow offspring?

In one gene, the dominant allele, B, produces black fur, and the recessive allele, b, produces brown fur.
