Biology Heredity

Having two different alleles for a trait.

• Homozygous

• Heterozygous

When an organism that has both alleles of a gene displays both phenotypes at the same time.

• Codominance

• Incomplete Dominance

• Dominant allele

• Recessive allele

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

Physical characteristics of organisms:

• Trait

• Gene

• Allele

• Probability
