. A black mare was crossed to a chestnut stallion andproduced a bay son and a bay daughter. The two offspring were mated to each other several times, andthey produced offspring of four different coat colors:black, bay, chestnut, and liver. Crossing a liver grandson back to the black mare gave a black foal,and crossing a liver granddaughter back to the chestnut stallion gave a chestnut foal. Explain how coatcolor is being inherited in these horses.

In horses, coat color comes in many varieties. If a brown horse is crossed with a white horse, the offspring are palominos (brown and white manes and tails). Name the type of inheritance. If a palomino horse is crossed with a white horse, what will the phenotype ratio of the F1 be?
In cattle, coat color is inherited in a co-dominant fashion. Homozygous C R C R produces red coat,homozygous C W C W produces white coat, and the heterozygous C R C W produces roan-colored coat.What is the probability of having a roan-coated offspring in a cross between a white-coated cattle anda roan-coated cattle?
What is a reciprocal cross? Suppose that a gene is found as a wildtype (functional) allele and a recessive mutant (nonfunctional)allele. What would be the expected outcomes of reciprocal crossesif a true-breeding normal individual was crossed to a true-breedingindividual carrying the mutant allele? What would be the results ifthe gene is maternally inherited?
In guinea pigs, short hair (L) is dominant to long hair (l), and the heterozygous conditions ofyellow coat (CY) and white coat (CW) give cream coat. A short- haired, cream guinea pig is bredto a long-haired, white guinea pig, and a long-haired, cream baby guinea pig is produced. Whenthe baby grows up, it is bred back to the short-haired, cream parent. What phenotypic classes, andin what proportions, are expected among the offspring?
Rabbits may be classified as agouti, chinchilla, Himalayan, or albino according to coat color. A crossbetween CC^h x C^ch c produced 5 agouti, 3 chinchilla and 2 Himalayans. a. What are the phenotypes of the parent rabbits? b. What are the genotypes of the F1s? c. What mode of inheritance is exhibited? d. If the two F1 agouti genotypes will be crossed, what percentage of their offspring will have the same phenotype? e. What will be the genotypes of the rabbits in (d)?
Duroc Jersey pigs are typically red, but a sandy variation is alsoseen. When two different varieties of true-breeding sandy pigswere crossed to each other, they produced F1 offspring that werered. When these F1 offspring were crossed to each other, they produced red, sandy, and white pigs in a 9:6:1 ratio. Explain this pattern of inheritance.
A rooster with a particular comb morphology calledwalnut was crossed to a hen with a type of comb morphology known as single. The F1 progeny all had walnut combs. When F1 males and females were crossedto each other, 93 walnut and 11 single combs wereseen among the F2 progeny, but there were also29 birds with a new kind of comb called rose and32 birds with another new comb type called pea.a. Explain how comb morphology is inherited.b. What progeny would result from crossing a homozygous rose-combed hen with a homozygouspea-combed rooster? What phenotypes and ratioswould be seen in the F2 progeny?c. A particular walnut rooster was crossed to a peahen, and the progeny consisted of 12 walnut,11 pea, 3 rose, and 4 single chickens. What are thelikely genotypes of the parents?d. A different walnut rooster was crossed to a rosehen, and all the progeny were walnut. What are thepossible genotypes of the parents?
Hair texture is determined by gene c in an incomplete dominance inheritance pattern, where the heterozygous condition (c1c2) results in wavy hair. Hairline is controlled by gene H, where a widow's peak is dominant to a straight hairline. If a woman with curly hair and a straight hairline has a child with a man with a widow's peak and straight hair (his mom had a straight hairline), what is the chance they would have a kid that has exactly the same hair as mom? Draw the Punnett square and demonstrate the possible genotypes and phenotypes that could result from these two parents' mating.
In humans, the ABO blood type is under the control of autosomalmultiple alleles. Red–green color blindness is a recessiveX-linked trait. If two parents who are both type A and have normalvision produce a son who is color-blind and type O, what isthe probability that their next child will be a female who has normalvision and is type O?
An alien friend named Tukan has two sets of eyes, one setforward-looking and one set backward-looking, and smooth skin.His mate, Valco, lacks eyes but has skin covered with tiny hooksthat attract all sorts of debris. Tukan and Valco have thrived onearth and have had four children, all with no eyes and smoothskin. Typical of their ways, the children interbred and produced 32children of their own.. Under the models of inheritance proposed by Mendel, identifywhich alleles are dominant and which are recessive.. Provide gene symbols that would reflect the dominant–recessiveallelic relationships..Of the 32 children, how many would you expect to have two setsof eyes and smooth skin?
In chickens, the Leghorn variety has white feathers due to an autosomal dominant allele. Silkies have white feathers due to a recessive allele in a second (different) gene. If a true-breeding whiteLeghorn is crossed to a true-breeding white Silkie, what is theexpected phenotype of the F1 generation? If members of the F1generation are mated to each other, what is the expected phenotypic ratio of the F2 generation? Assume the chickens in the parental generation are homozygous for the white allele at one gene andhomozygous for the brown allele at the other gene. In subsequentgenerations, nonwhite birds will be brown.
The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
