a student claims that dominant traits are always the most comom traits. Is this true why or why not

yes dominant traits are called dominant because they are the most common
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
no, dominant traits only show up if they are inherited; how common they are is not influenced by this
yes, dominant traits became fore common over timeas they are passed down from generation to generation; recessive alleles continue to become less common over time

The correct answer 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 called dominant because they are expressed in the phenotype when present. However, their frequency in a population is not necessarily related to their dominance. Dominant traits can be less common in a population because they can be caused by a rare allele and can persist due to the advantage they confer. On the other hand, recessive alleles can be more common in a population but may not be expressed in the phenotype unless an individual inherits two copies.
