  • Complete dominance

    Heterozygous and homozygous individuals show the same phenotype.

  • Incomplete dominance

    The phenotype of heterozygotes is intermediate between the two homozygous parents.

  • Co-dominance

    Both alleles are expressed equally and distinctly in the phenotype of heterozygotes.

  • Multiple alleles

    Most genes exist in populations with more than two allelic forms.

  • Pleiotropy

    A single gene influences multiple, seemingly unrelated phenotypic traits.

  • Epistasis

    A gene at one locus alters or masks the phenotypic expression of a gene at a different locus.

  • Polygenic inheritance

    The additive effect of two or more genes on a single phenotypic trait.
