• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

How do artificial selection and natural selection differ?

• In artificial selection, the environment acts as the selecting agent.

• In natural selection, traits that are useful to humans are inherited.

• In natural selection, humans act as the selecting agent.

• In natural selection, the environment acts as the selecting agent.
