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

Question

Responses

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.

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.

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 dominance refers to the relationship between alleles, not their frequency in the population. A dominant allele does not necessarily mean that it is more common; for instance, some dominant traits can be rare, while recessive traits can be more widespread. The persistence of a trait in a population is influenced by various factors including natural selection, genetic drift, and mutation rates, rather than the dominance relationship alone.
