• Adaptation
• Evolution
• Natural Selection

Why are advantageous traits more likely to be passed onto offspring?

• Because organisms with those traits are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired (learned) phenotype.
