Answer 1

The correct response is:

No, dominant traits only show up if they are inherited; how common they are is not influenced by this.

This answer highlights that while dominant traits can express more readily when present, the frequency of a trait in the population depends on various factors, including genetic variation, mutation rates, and selection pressures, rather than the dominance itself. Dominant traits are not necessarily more common than recessive traits.
