traits that are controlled by two or more genes

the trait that is visibly expressed in an organism when two different alleles are inherited for a gene

• dominant

• recessive

• phenotype

• genotype

the study of inherited traits

• biology

• zoology

• genetics

• genealogy

the set of genes, including alleles from both parents, which determines the expression of an organism's characteristics or traits

• phenotype

• recessive

• incomplete dominance

a situation in which the phenotypes produced by both alleles are completely expressed

• codominance

• dominant
