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 a breeder mates two dogs that are heterozygous for the hair allele. Draw a Punnett square to predict the genotypic and

In pigeons, the checkered pattern is dependent on a dominant gene C and a plain exterior on the recessive allele c. Red color is controlled by a dominant gene B and brown by the recessive allele b. Diagram completely a cross between homozygous checkered, red birds and plain, brown birds. Summarize the expected F2 results.
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 guinea pigs, the allele for a rough coat (R) is dominant over the allele for a smooth coat (r). A heterozygous guinea pig (Rr) and a homozygous recessive guinea pig (rr) have a total of nine offspring. The Punnett square for this cross shows a 50 percent chance that any particular offspring will have a smooth coat. Explain how all nine offspring can have smooth coats.arrow_forwardIn 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.

Use W for the long whiskers allele and W* for the short whiskers allele. You cross a true-breeding FEMALE with long whiskers to a true-breeding MALE with short whiskers. After intercrossing the F1 progeny, which of the following results are expected for the resulting F2 progeny? a) None of these choices b) 3/8 of the F2 progeny will be males with short whiskers. c) All of these choices d) 1/8 of the F2 progeny will be females with short whiskers. e) 3/8 of the F2 progeny will be females with long whiskers.
