Which statement explains the difference between dominant and recessive traits?

• Dominant traits are observable traits that mask the recessive form of a trait, while recessive traits are masked by the dominant trait.

• Dominant traits are masked by the recessive trait, while recessive traits are observable traits that mask the dominant form of a trait.

• Dominant traits provide the genetic description of an organism, while recessive traits describe the way the organism looks and behaves.

• Dominant traits describe the way the organism looks and behaves, while recessive traits provide the genetic description of an organism.
