What does the term polled mean in a cow?
The term "polled" refers to cattle that naturally lack horns. In these animals, the genetic trait for hornlessness is inherited, meaning they do not develop horns as part of their anatomy. Polled cattle are often bred selectively for this trait, as it can reduce the risk of injury to other animals and handlers. This trait is common in several breeds, including the Polled Hereford and some strains of Angus.
Which individuals have a trait that is traced by the pedigree?
Individuals with a trait traced by a pedigree are typically those who express the trait, either as affected individuals or carriers.

By analyzing the connections between generations and the presence of the trait, one can identify how the trait is passed down and which individuals have it.

What is the difference between a derived trait and an ancestral trait in terms of evolutionary biology?

Derived traits are unique to a particular species and can help distinguish it from others, while ancestral traits are shared among related species.
