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

Question

Responses

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 more common over time as they are passed down from generation to generation; recessive alleles continue to become less common over time.

Answer 1

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 is true because the frequency of a trait in a population is influenced by various factors, including natural selection, genetic drift, mutation, and gene flow, rather than just dominance. A dominant allele does not necessarily have to be the most common; it can be less common than recessive alleles while still being dominant.
