Step 1
For example, if the trait is horn presence, a heterozygous genotype would be Hh, where H is the dominant allele for horns and h is the recessive allele for no horns. Show more…

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?

Some cattle are naturally hornless, a condition called polling. Polling is dominant over the more common horned trait. A polled bull is mated with three female with the following offspring: Female Cow A = polled calf Female Cow B = horned calf Female Cow C = horned calf What are the genotypes of the 4 parents?
