A genetic factor that blocks another genetic factor.

• dominant trait

• recessive trait

• phenotype

• genotype

A genetic factor that is blocked by the presence of a dominant factor.

• Dominant trait

• Recessive trait

• Gene

• Allele

Codominance

• A model used to predict possible genotypes and phenotypes of off spring

• The study of how traits are passed from parents to offspring

• When both alleles can be observed in a phenotype

• When the offspring's phenotype is a combination of the parents' phenotypes

Incomplete dominance

• when the two alleles of a gene are the same

• when the two alleles of a gene are different

• when the offspring's phenotype is a combination of the parents' phenotypes

• when both alleles can be observed in a phenotype

Punnett Square

• a genetic factor that blocks another genetic factor

• a genetic factor that is blocked by the presence of a dominant factor

• physical appearance of a trait

• a model used to predict possible genotypes and phenotypes of offspring
