Almost all adaptations started off as?

• selective breeding

• physiological

• structural

• mutations

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

• Because those traits make them more likely to survive and reproduce.

• Because those traits come from dominant alleles.

• Because those traits come from recessive alleles.

• Because those traits are acquired phenotypes.
