• mutation

• camouflage

• adaptation

Which organisms are most likely to survive?

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

The differences among a species, like different bird beaks, are called

• genes
• variations
• traits
• theories
