Question

a student claims that dominant traits are always the most common traits. is this true? why or why not? (1 point)
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.
yes, dominant traits are called dominant because they are the most common.
no, dominant traits only show up if they are inherited; how common they are is not influenced by this.
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.

Explanation:

Dominance refers to the expression of a trait when present in an allele combination. Frequency of a trait in a population depends on many factors like selection pressures, not just dominance. A dominant trait only shows up if inherited and its prevalence isn't determined by its dominance - recessive traits can be more common if they have a selective advantage.

Answer:

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