Complex Patterns of Inheritance

By: Tyrique Elmore

Multiple Alleles

Def-Traits controlled by more than 2 alleles.

There are mutated phenotypes

1 example is the different blood types another is the color of rabbits depending on where they are.

Incomplete Dominance

Def- Neither gene is completely expressed over the other.

Offspring often heterozygous and are a blend of the 2 parents


Def- Both alleles are present and visable.

Heterozygous offspring show both alleles clearly.

Polygenic Traits

Def-Trait is controlled by nonallelic genes

Phenotypes include skin color and height
