In man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a marriage between a heterozygous spotted, non-wooly man with a heterozygous wooly-haired, non-spotted woman. Give genotypic and phenotypic ratios of offspring.
In horses, black is dependent upon a dominant gene, B, and chestnut upon its recessive allele, b. The trotting gait is due to a dominant gene, T, the pacing gait to its recessive allele, t. If a homozygous black pacer is mated to a homozygous chestnut trotter, what will be the appearance of the F1 generation?
In hamsters, black fur (B) is dominant over brown fur (b) and long fur (L) is dominant over short fur (l). A black, long furred female whose mother had brown fur and whose father had short fur is mated with a black, short furred male whose father had brown, long fur.
What is the probability that the first three offspring will have brown, long fur?
What is the probability that the first offspring will have black, long fur?
What is the probability that one of the first three offspring will have black, long fur and the other two brown, short fur?
In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?

- In 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_forwardIn Dogs, short tail (t) is recessive to long tail (T). A true-breeding (homozygous) short-tailed male is mated to a long-tailed female. What will the phenotype of their juvenile dog look like? * TT Tt tt All will have Long tail (Homozygous) All will have Long tail (Heterozygous) All will have short tail (Homozygous)arrow_forwardIn rural northeast Kansas domesticated cats are becoming wild, and biologists are observing that wildcats occur in three colors. Fur color is controlled by a single gene that exhibits incomplete dominance. A homozygous dominant cat is blue (BB), a homozygous recessive cat is red (bb), and a heterozygous wildcat will be purple (Bb). What would be the expected phenotypes of the offspring if a blue wildcat mates with a red wildcat? Develop a Punnett square and list the genotypes as well.arrow_forward
- In a particular animal, coat color is under the control of two interacting genes. Each gene has a dominant and recessive allele. A = Color, a = Albino, and B = Brown coat color, b = Red coat color. Two AaBb animals are mated. What proportion of their offspring is expected to be albino? Assume the genes are assorting independently.arrow_forwardIn seals, long whiskers (W) are dominant over short whiskers (w). What are the genotypic and phenotypic ratios for the offspring produced by mating a seal that is homozygous recessive with one that is heterozygous?arrow_forwardIn Labrador dogs, coat color is controlled by the genotypes of two genes. In one gene, the dominant allele, B, produces black fur, and the recessive allele, b, produces brown fur. However, if a second gene possesses two recessive alleles, ee, the dog produces yellow fur, regardless of the genotype of the first gene. If two dogs that are heterozygous for both genes, BbEe mated, what would be the frequency of the three phenotypes, black, brown, and yellow?arrow_forward
- In cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black? What percent of their offspring will be tortoise shell?arrow_forwardIn dogs, black fur color is dominant to white. Two heterozygousblack dogs are mated. What is the probability of the followingcombinations of offspring?A. A litter of six pups, four with black fur and two with white fur.B. A first litter of six pups, four with black fur and two with whitefur, and then a second litter of seven pups, five with black furand two with white fur.arrow_forwardIn Andalusian chickens, feather côlor is inherited by incomplete dominance. If one parent with black feathers (BB) is crossed with a white feathered parent (WW), all of the offspring will have blue feathers (BW).

When a parent with blue eyes (bb) mates with a parent heterozygous for brown eyes (Bb), what is the expected genotypic ratio of their offspring?arrow_forwardIn aliens, blue skin is dominant and green skin is recessive. Round bodies are dominant and square bodies are recessive. An alien who is heterozygous for both characteristics is mated with another alien who is purebred for both recessive traits.
