Chapter 12.2, Problem 1SB
Palomino horses have a golden coat color, with a white mane and tail. Palominos do not breed true. Instead, there is a 50% chance that a foal with two Palomino parents will be a Palomino. What is the explanation?

In horses, B=black coat, b=brown coat, T=trotter, and t=pacer. A black pacer mated to a brown trotter produces a black trotter offspring. What is the genotype for this offspring.
Horses can be cremello (a light cream color), chestnut (a reddish-brown color), or palomino (a golden color with white in the mane and tail). Of these phenotypes, only palominos never breed true. The following results have been observed:
Cremello x palomino > 50% cremello, 50% palomino
Chestnut x palomino > 50% chestnut, 50% palomino
Palomino x palomino > 25% chestnut, 50% palomino, 25% cremello
From these results, determine the appropriate allele symbols and indicate which genotypes lead to which phenotypes.
Predict the F1 and F2 phenotype ratios of a cremello x chestnut P generation cross.
Fur color is codominant in cows. A roan cow has a fur color of orange and white. What are the phenotype and genotypic ratios expected if a roan male and a roan female breed together?

- In British cattle, those with long legs are called Kerry and others with extremely shortened legs are called Dexter. When Kerry cattle are crossed, their progeny have only the Kerry phenotype. When Dexter cattle are crossed with Kerry cattle, they produce Kerry and Dexter phenotypes in a 1:1 ratio. When Dexter are crossed with Dexter, 1/4 of the offspring are Kerry, 2/4 are Dexter, and 1/4 are born dead with very short legs and nose (bulldog phenotype). Interpret the genetics of the Kerry and Dexter phenotypes.arrow_forwardIn horses, the coat color black is dominant (B) over chestnut (b). The trotting gait is dominant (T) over the pacing gait (t). If a homozygous black pacer is mated to a homozygous chestnut, heterozygous trotter, what will be the ratios for genotype and phenotype of the F1 generation?arrow_forwardIn horses, black coat (B) is dominant to brown coat (b), and being a trotter (T) is dominant to being a pacer (t). A black pacer is crossed with a brown trotter. The offspring is a brown pacer. Give the genotypes of all of these horses. Show a punnet square if neededarrow_forward
- A man has a roan bull and a white cow. His first 5 calves turned to be 2 roans and 3 white. Keeping in mind the fact that the roan is a color obtained when cattle are heterozygous for the gene for red and white, how frequently (probability of the phenotypes) would you expect such as a combination of offspring as that obtained in this case?arrow_forwardYou are a cat breeder and was asked to choose two parents (male and female) among a group of cats with different coat colors: black, orange and calico. What coat color parents (male and female) would you choose to maximize the chance of getting calico kittens in a litter? Illustrate and explain your choice with the selected cross and outcomes.arrow_forwardIn shorthorn cows, neither the red-haired gene (R) nor the white-haired gene (r) is dominant. A hybrid cow displays a roan color. A pure red cow and crossed with a pure white bull. What are the possible genotypes and phenotypes and their likelihood of appearance? Dam Genotype Sire % chance in offspring Phenotype % chance in offspringarrow_forward
- In horses, black coat color (B) is dominant over roan coat color (b), and a trotter (T) is dominant over a pacer (t). A black trotter mare was bred with a stallion to produce a roan pacer colt. Determine the genotypes of the colt and mare and all the possible genotypes for the stallion. What is the highest probability for the stallion’s genotype?arrow_forwardThere is a lack of dominance in black and white horse coat colours. An offspring produced from a black horse and a white horse has a blue-roan coat colour. When the blue-roan coat is closely examined, both black and white hair can be found. A black horse mated with a blue roan horse. Which of the following alternatives correctly identifies the phenotypic ratio of the offspring? Select one: a. 1 BB : 1 BW b. 1 white : 1 black c. 1 black : 1 blue roan d. 1 WW : 1 BBarrow_forwardIn shorthorn cattle (S), when a red bull is crossed with a white cow, all the offspring are roan—a spotted, red and white or milky red color. What offspring are expected from mating a roan bull and a roan cow? Show the Punnett Square.arrow_forward
- In the image a Brown coated horse is crossed to a White coated horse and the resulting offspring has a Palomino coat. What Genetic characteristic causes this offspring coat color?arrow_forwardBackground: In certain types of cattle, three colors exist: white (WW), white hairs red hair (RR), red hairs roan (RW), a mixture of red and white hairs Roan is a codominant condition. Question: A breeder wants to only produce roan-colored cattle. Which of the following parents should she select to only produce roan-colored offspring? Select all that apply. a black-haired parent b white-haired parent c roan-haired parent d red-haired parentarrow_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. What is the percent chance of having blue, square-bodied offspring?arrow_forward
