In cats, the allele for black coat color is codominant with the allele for yellow coat...

In cats, the allele for black coat color is codominant with the allele for yellow coat color, and is located on the X chromosome. If a cat gets alleles for black and yellow coat, it will have a mottled coat that contains both yellow and black coloring known as Tortoise shell. A tortoise shell female mates with a yellow male.

a) What is the genotype of each parent?

b) Draw a Punnett square that shows this cross.

c) What is the chance of having a tortoise shell male offspring from this cross?

d) What is the chance of having a tortoise shell female?

1. In cats, coat color is controlled by a gene on the X chromosome. Yellow coat color is determined by the b allele and black coat color is determined by the B allele. The heterozygous condition results in a color known as tortoise shell. a. What phenotypic ratio of offspring would be expected from a cross between a yellow male and a tortoise-shell female? b. What proportion of the female offspring from a cross between a black female and a...

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 mice the allele for black coat color (B) is dominant to the allele for white...

In mice the allele for black coat color (B) is dominant to the allele for white coat color (b). The allele for long tail (T) is dominant to the allele for short tail (t). For the same cross: BbTt x bbTt a. Using the Probability Method illustrated in lecture, break the complex two-gene cross into two simple single-gene crosses (note that the Probability Method can be used if it is known that the alleles of the different genes Assort...

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 mice the allele for blue coat color (B) pink coat color (b). The allele for long tail (T) is dominant of the allele for short tail (t). 1) If alleles of the two genes Assort Independently, what types of gametes will BbTt mice produce? What is the expected frequency of each gamete among all gametes produced?

In cats with tortoiseshell coat color, the fur is white with patchy black and orange spots....

In cats with tortoiseshell coat color, the fur is white with patchy black and orange spots. In cats, the tortoiseshell gene is on the X chromosome, and the tortoiseshell phenotype requires the presence of 2 different alleles at this locus: one for orange fur (o) and one for black fur (b). Which phenomenon best explains why female cats can inherit tortoiseshell coat color? (A. In females, the alleles for coat color are pleiotropic, resulting in patches of orange and black...

Labrador retriever dogs have three coat colors: black, brown and yellow. The color of the pigment deposited in the hairs is determined by a gene with two alleles (B or b). The B allele codes for black pigment and is dominant to the b allele which codes for brown. Another gene with two alleles (E or e) determines if the pigment created will be deposited into the hairs. If both copies (ee) are recessive, no pigment will be deposited (regardless...

The coat color in mink is controlled by two codominant alleles at a single locus. Red coat color is produced by the genotype R1R1, silver coat by the genotype R1R2, and platinum color by R2R2. White spotting of the coat is a recessive trait found with the genotype ss. Solid coat color is found with the S- genotype. Two crosses are made between mink. Cross 1 is the cross of a solid, silver mink to one that is solid, platinum....

In rats, gene B produces black coat color if the genotype is B-, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D-, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. A third independently assorting gene involved in determination of coat color in rats is...

In rats, gene B produces black coat color if the genotype is B–, but black pigment...

In rats, gene B produces black coat color if the genotype is B–, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D–, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. Determine the genotypes of parents of litters with the following phenotype distributions. Part A...
