|
Incomplete dominance
|
heterozygotes have a phenotype intermediate to the two alleles (Gray between black and white)
|
|
|
Co-Dominance
|
the phenotype of both alleles is fully expressed in heterozygotes. (Blood type AB)
|
|
|
Penetrance
|
the probability that a mutation will manifest its phenotype
|
|
|
Expressivity
|
how strongly a phenotype is expressed
|
|
|
Epistasis
|
a gene at one locus alters the phenotypic expression of a gene at a second locus (hair color and baldness. Having baldness will make hair color not matter)
|
|
|
Multiple Alleles
|
more than two alleles affect a phenotype
|
|
|
Pleiotropy
|
one gene affects > one phenotypic character
|
|
|
Polygenic Inheritance
|
multiple genes are responsible for a phenotype
|
|
|
Environmental Impact
|
genetically identical individuals show different phenotypes as a result of environmental factors.
