Black fur color is dominant to white fur color and non-webbed toes are dominant to webbed toes. a dog with white fur and web toes is mated with a dog homozygous dominant for both black fur and non-webbed toes. Draw the resulting Punnett square from this cross. What are the genotypic and phenotypic ratios of their offspring.

Expert Solution

Black fur color - BB.

White fur color - bb.

Non-webbed toes - WW.

Webbed toes - ww.

Dog with white fur and web toes - bbww.

Dog homozygous dominant for both black fur and non-webbed toes - BBWW.

Parent generation - BBWW X bbww

Gametes formed BW bw

F1 generation BbWw(black fur and non-webbed toes) X BbWw

Gametes formed BW, Bw, bW and bw BW, Bw, bW and bw

F2 generation

Male/ Female	BW	Bw	bW	bw
BW	BBWW(black fur and non-webbed toes)	BBWw(black fur and non-webbed toes)	BbWW(black fur and non-webbed toes)	BbWw(black fur and non-webbed toes)
Bw	BBWw(black fur and non-webbed toes)	BBww(black fur and webbed toes)	BbWw(black fur and non-webbed toes)	Bbww(black fur and webbed toes)
bW	BbWW(black fur and non-webbed toes)	BbWw(black fur and non-webbed toes)	bbWW(white fur and non-webbed toes)	bbWw(white fur and non-webbed toes)
bw	BbWw(black fur and non-webbed toes)	Bbww(black fur and webbed toes)	bbWw(white fur and non-webbed toes)	bbww(whitefur and webbed toes)

The genotypic ratio - 1BBWW: 2BBWw: 2BbWW: 4BbWw: 1BBww: 2Bbww: 1bbWW: 2bbWw : 1bbww.

The phenotypic ratio - 9 black fur and non webbed toes : 3 black fur and webbed toes: 3 white fur and non-webbed toes: 1 whitefur and webbed toes.

in badgers, fur color is inherited through simple autosomal inheritance, and black fur is dominant to white fur. A black badger is crossed with a white badger. In a cete of four kits, all of the kits are black. You have asked to draw a conclusion about the black badger. What is the best conclusion you can draw from this data? a. The black badger is definitely homozygous. b. the black badger is probably homozygous. c. the black badger is...

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...

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...

A female mouse that is heterozygous for fur color where dark fur is dominant to light fur and homozygous dominant for long-tail length is mated with a male that is heterozygous for both traits. How many genotypes will be represented in the F1 generation? A. 1/32 B. 1/16 C. 1/8 D. 1/4 E. 1/2

In rabbits, black fur (B) is dominant over brown fur (b). Normal length fur is determined...

In rabbits, black fur (B) is dominant over brown fur (b). Normal length fur is determined by a dominant gene (R) and a short “rex” by the recessive allele (r). Draw a cross between a homozygous black with homozygous normal length fur and a brown rex rabbit. Do a cross of the F1 generation to determine the phenotypes and genotypes of the F2 generation.

In the shrub Ixococ meloites, red flower color is incompletely dominant to white flower color. If a true-breeding plant with red flowers is crossed to a true breeding plant with white flowers, what would be the phenotype of the F1 plants? a. The plants will all have red flowers. b. The plants will all have white flowers. c. The some of the flowers on an F1 plant will be red and other flowers on the same plant will be white....

4.In dancing bears, short fur is dominant to long fur, and curly hair is dominant to straight. The genes for these traits are located on separate autosomes. You have a large population of dancing bears with the following allele frequencies Short fur (S) p = 0.5, Long fur (s) q = 0.5 Curly hair (C) p = 0.3, Straight hair (c) q = 0.7 You allow the population to randomly breed for several generations. You have a population of 1000...

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 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
