An organism's physical appearance or visible traits:

• Genotype

• Phenotype

Having two identical (same) alleles for a trait.

• Homozygous

• Heterozygous

Having two different alleles for a trait.

• Homozygous

• Heterozygous

When the phenotype of the two alleles blend.

• Codominance

• Incomplete Dominance

• Dominant allele

• Recessive allele

Inherited traits that are determined by more than one gene.

• Codominance

• Incomplete Dominance

• Polygenic Traits

• All are incorrect

What are the letters that are the pair of alleles of an organism's genes called?

• Phenotype

• Genotype

• Alleles

This is another word for the physical traits being observed. They are determined by the Genotype.

• Traits

• Inherit
