Answer 1

No, dominant traits are not always the most common traits. Dominant traits are called dominant because they are expressed in individuals even when only one copy of the dominant allele is present. However, the frequency of a trait in a population is not solely determined by whether it is dominant or recessive. The occurrence of a trait is influenced by various factors, including genetic variation, mutation rates, selection pressures, and population size. Therefore, it is possible for recessive traits to be more common in a population than dominant traits.
