Question

he polled trait is dominant, and offspring of a polled bull will also be polled, even though the dams have horns.

True

False

Answer 1

True. In genetics, if the polled trait is dominant, then a polled bull (which has at least one allele for the polled trait) can produce polled offspring, even if the dams have horns (which would be homozygous recessive for the horned trait). The presence of the dominant allele from the bull would result in polled offspring.
