A student claims that dominant traits are always the most common traits. Is this true? Why or why not?(1 point)

Responses

Yes, dominant traits became more common over time as they are passed down from generation to generation; recessive alleles continue to become less common over time.

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

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.

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.

This response highlights that dominance does not equate to prevalence. A trait can be dominant but still be rare in a population if the recessive allele for the trait is more common. The frequency of a trait in a population is influenced by many factors, including the genetic basis of the traits, selection pressures, and mutation rates, rather than simply the dominance or recessiveness of the alleles.
