Question

Are dominant traits always the most common trait?

Answer 1

No, dominant traits are not always the most common trait. Dominant traits are characterized by being expressed in individuals even with one copy of the dominant allele, while recessive traits require two copies of the recessive allele for expression. However, the frequency of a trait in a population is not solely determined by its dominance or recessiveness. Factors such as genetic variation, mutation rates, gene flow, natural selection, and random genetic drift also influence the prevalence of traits in a population. Therefore, a dominant trait may or may not be more common than a recessive trait, as it depends on various complex genetic and environmental factors.
