Term
MUTATIONS
Definition
Rare stable, and inherited changes in the genetic material. Alleles can mutate to become a different allele.

WILD TYPE
Definition
The one allele that is present in most individuals in nature ("the wild") and gives rise to an expected trait or phenotype.
Term
POLYMORPHIC
Definition
(Greek poly, "many"; morph "form"). A genetic locus with a wild type allele that is present less then 99 percent of the time is said to be polymorphic.
Term
INCOMPLETE DOMINANCE
Definition
Occurs when heterozygotes show a phenotype that is intermediate between those of the two homozygotes.
Term
CODOMINANCE
Definition
Occurs when two alleles at a locus produce two different phenotypes that both appear in heterozygotes. Ex: ABO blood type
