The correct answer 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 because the dominance of a trait is determined by its ability to express itself in the presence of a recessive allele. Dominant traits can appear less frequently in a population compared to recessive traits, but they are able to persist because they can be expressed even if only one copy of the allele is present. In contrast, recessive traits require two copies of the allele to be expressed. Thus, the frequency of a trait in a population is not solely determined by its dominance.
A student claims that dominant traits are always the most common traits. Is this true? Why or why not? (1 point)
O Yes, dominant traits are called dominant because they are the most common.
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.
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.
