Chapter 9, Problem 8TYK
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

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.
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 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? Hint: draw your square on a
separate paper to figure it out.

- 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?arrow_forwardIn humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A). What is the genotype of someone who has cystic fibrosis? What are the two different genotypes that a healthy person could have? If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.arrow_forwardIn humans, hair color and structure are determined by two independent pairs of genes. The dominant gene T determines dark hair color, and the recessive allele t - light hair; The dominant gene S determines the formation of curly hair, and its recessive allele t - straight hair. What kind of hair will the children have if the mother has light, straight hair, and the father has dark, curly hair (one of the pairs of traits is heterozygous for both parents)?arrow_forward
- Skin color in humans is determined by polygenic inheritance, which means the more dominant alleles there are, the darker the skin color will be. A medium-toned skinned woman (AaBb) has a child with another medium-toned skinned man (AaBb). What is the probability of them having a very dark-toned skinned child? (Hint: the genotype is homozygous dominant)arrow_forwardA common kind of red-green blindness in humans is caused by the presence of a sex-linked recessive gene c, whose normal allele is c+. Using these genes, what are the possible genotypes and their corresponding phenotypes in males and females? Can two colorblind parents produce a normal son? (b) A normal daughter? (c) Can two normal parents produce a colorblind son? (d) a colorblind daughter?arrow_forwardIn cats, there is a gene that codes for fur colour on the X chromosome. One allele gives black fur, and the other gives orange fur. A cat that has one of each allele (heterozygous) has fur that has large patches of orange and large patches of black. This fur colour is called tortoiseshell (A) a) is this strict Mendelian, incomplete dominance, or co-dominance? (Choose only one and explain) b) is it possible for male cats to have the tortoiseshell fur colour? Explain. If a female fruit fly homozygous for white eyes is crossed with a red-eyed male, what percentage of the offspring would have white eyes? (eye colour is x-linked and white is recessive) a) 100% b) 0% c) 50%. d) 25%arrow_forward
- In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b. Short hair (H) is dominant to long hair (h). In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like? If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype If you carried out this test cross, what phenotypes and in what ratio would you expect?
