The correct response is: No, dominant traits in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles.
Dominant traits are not necessarily the most common traits in a population. A dominant trait can be rare if the allele that causes it is infrequently inherited, while recessive traits can be more common even if they are not expressed unless inherited from both parents. The frequency of traits in a population is influenced by various factors, including genetic drift, mutation rates, and selective pressures, and not solely by whether they are dominant or recessive.
