the form of a trait that masks another trait

• recessive

• dominant

refers to an organism that has two of the same alleles for a trait; another term for purebred (Ex: TT or tt)

• homozygous

• heterozygous

refers to an organism that has two different alleles for a trait; another term for hybrid (Ex: Tt)

• homozygous

• heterozygous

refers to how an organism will look based on its genes

• genotype

• phenotype
