Explain the difference between dominant and recessive traits.

• Dominant traits are expressed with one allele, while recessive traits require two alleles.

• Dominant traits require two alleles, while recessive traits are expressed with one allele.

• Dominant traits can only be inherited from one parent, while recessive traits can be inherited from both.

• Recessive traits are always more common than dominant traits.
