Chapter 10, Problem 2GP
In Mexican hairless dogs, a dominant allele confers hairlessness. However, inheriting two dominant alleles is lethal; the fetus dies before birth. Suppose two dogs that are heterozygous for the hair allele mate. Predict the genotype and

In Manx cats, the alleles TT yield a cat with normal long tail. The alleles Tt yield a cat with a shirt or absent tail, and the alleles tt are lethal to an embryo. Predict the genotypes and phenotypes of potenjtal kittens resulting from the mating of 2 short-tailed cats.
In Dalmatians, black spots are dominant to the condition of not having black spots. A black-spotted male
whose mother did not have black spots is mated with a female that has no spots.
They produce a litter of 6 puppies. Using a Punnett square, predict the number of
each phenotype of puppy. Don't forget to define the alleles.
The fur colour of Labrador dogs is determined by three alleles: black (FB), chocolate
(F), and yellow (FY). If black is dominant to yellow, and chocolate is dominant to
yellow, what will the puppy colours be if a heterozygous chocolate Labrador and a
yellow Labrador are bred? Use a Punnett square to support your answer.

- In a certain breed of dogs, a gene (L) codes for hair length. The dominant trait is short hair and the recessive is long hair. Suppose a heterozygous female dog and a homozygous recessive male dog mate. What is the male dog’s genotype and the female dog’s genotype? What is the male dog’s phenotype and the female dog’s phenotype? What will be the genotypic ratio for the offspring from these dogs? What will be the phenotypic ratio for the offspring from these dogs?arrow_forwardIn otters fur colour can be either yellow or brown, and is determined by two alleles of the C gene. A heterozygous otter is observed to present a fur pattern of yellow and bear patches. Explain why this can occur.arrow_forwardFor a particular rodent, black fur is dominant over brown fur, and a long tail is dominant over a short tail. Give the possible genotypes and phenotypes of the possible offspring that could result from the breeding of a homozygous black fur and heterozygous tail rodent and a rodent of heterozygous for both traits.arrow_forward
- In Minx cats, the alleles TT yield a cat with a normal tail, the heterozygous alleles Tt yield a cat with a short tail or no tail at all, and the recessive alleles tt are lethal to the embryo. Using Punnett squares, determine the genotypes and phenotypes of all offspring from parent Minx cats that both have short-tails.arrow_forwardIn some cats, the gene for tail length shows incomplete dominance. Cats homozygous for the long tail allele (T) have long tails and cats homozygous for the short tail allele (t) have no tails. Heterozygous cats have short tails. Draw a Punnett square for a mating between a short tail cat and a cat with no tail. According to your Punnett square, what is the percent chance that they would have a kitten with no tail? A)0% B)25% C)50% D)75% E)100%arrow_forwardSuppose the ear length of two populations of jerboas is controlled by one gene. To determine the mode of inheritance, a homozygous short-eared female is crossed with a homozygous long-eared male. Then, siblings from the F₁ are crossed, and the number of short- and long-eared animals are counted to determine the phenotype ratio. Match the phenotypic ratio anticipated in the offspring from a cross of two heterozygous individuals to the appropriate mode of inheritance for the short-ear allele. Mode of inheritance F1 phenotype Cross of heterozygotes 1 long : 3 short Autosomal dominant Autosomal recessive Sex-linked dominant Sex-linked recessive All short-eared 1 long : 1 short All long-eared Answer Bank All short-eared males 1 long : 1 short; females all short 3 long : 1 short Long-eared females, short-eared malesarrow_forward
- Hairlessness in dogs is inherent in a single dominant allele. Inheriting two dominant alleles is lethal for an embryo. Penelope, a hairless dog mates with Arnold, a hairless dog. The probability that Penelope has hairless puppies isarrow_forwardSuppose the allele frequency for a dominant allele is 0.81 and the frequency of the recessive allele is 0.19. Calculate the frequencies for the homozygous dominant, heterozygous, and homozygous recessive genotypes.arrow_forwardHair length is incompletely dominant in Chihuahuas. If a homozygous long-haired Chi mates with a homozygous short-haired Chi, their heterozygous offspring have medium-length hair. If two heterozygous Chihuahuas mate, what is the probability that their pups will have long hair, medium hair, or short hair? L = long hair allele l = short hair allelearrow_forward
- Please use instructions from above Red roan hair colour in some horses is due to codominance of the white allele and the red allele. If a red roan horse mates with a white horse, indicate the genotypic and phenotypic ratios that would result.arrow_forwardLabrador retrievers have 3 varieties of fur colour: yellow, chocolate or black. Two genes are involved, each with a dominant (Y and B) and a recessive allele (y and b). The allele Y codes for the ability to produce hair pigment: Yy and YY dogs have dark pigmented fur but all yy individuals are lighter coloured and yellow. The B allele codes for the ability to make hair with the darkest colouration: BB and Bb individuals have black fur; bb dogs have a lighter shade which is chocolate. In the blank Punnet Square below, calculate and state the ratio of phenotypes that occur with a cross between two individuals with the genotype YyBb.arrow_forwardRoan cattle show codomiance for the color of their hair. There are allele for red hair and white hair what would you expect a heterozygous roan bull to look like if the trait showed incomplete dominance insteadarrow_forward
