Use the following information to answer the next two questions. In cattle, a polled or hornless trait (P) is dominant over a horned trait(p). A polled bull mated with three different cows, and the following calves were born in the spring. Cow Phenotype | F1 Generation Phenotype Cow 1 - Horned | Calf 1 - Horned Cow 2 - Polled | Calf 2 - Horned Cow 3 - Polled | Calf 3 - Polled Which of the following rows correctly identifies the genotypes of the cattle? Select one: a. Cow 1 - pp | Bull - PP b. Cow 3 - Pp | Calf 3 - pp c. Bull - Pp | Calf 2 - pp d. Cow 2 - pp | Calf 1 - Pp

In cattle, the polled (hornless) condition is dominant over the horned phenotype. A particular polled bull is bred to three cows. With cow A, which is horned, a horned calf is produced; with a polled cow B, a horned calf is produced; and with horned cow C, a polled calf is produced. What are the genotypes of the bull and the three cows, and what phenotypic ratios do you expect in the offspring of these three matings? (Use P for the polled allele and p for the horned allele.)

The polled or hornless condition (P) is dominant over the horned (p) condition. A certain polled bull is bred to three cows. Predict the genotypes of each of the following: (a) polled bull X horned cow produces polled calf (b) polled bull X horned cow produces horned calf (c) polled bull X polled cow produces horned calf
