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.
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 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 — correct choice: "No, dominant traits only show up if they are inherited; how common they are is not influenced by this."
Explanation: "Dominant" describes how an allele affects the phenotype in a heterozygote, not how frequent the allele is in a population. Allele frequency is determined by selection, mutation, drift, migration, etc. For example, Huntington disease is caused by a dominant allele but is rare; many recessive traits (or alleles) can be common in a population.
