Question

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 are called dominant because they are the most common. 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 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. 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.

Dominance refers to the relationship between alleles, where a dominant allele masks the expression of a recessive one in a heterozygous individual. However, the frequency of traits in a population is influenced by various factors, including genetic drift, mutation, natural selection, and other evolutionary processes. As a result, dominant traits can be less common despite their dominant nature, and recessive traits can be more prevalent in specific populations.
