Non-Mendelian Genetics

Having 2 or more alleles that are equally dominant and BOTH traits are expressed.

• incomplete dominance

• Codominance

• complete dominance

• Multiple alleles

Having alleles that do NOT have complete dominance; results in a MIX of the traits

• Codominance

• multiple alleles

• incomplete dominance

• polygenic traits

A cross that shows a different trait for the offspring than the parent's traits

• incomplete dominance

• complete dominance

• recessive

Both genes are expressed; example is having black and white fur

• recessive

• incomplete dominance

• codominance

Genetic disease caused by codominant gene; hemoglobin in blood is wrong shape.

• anemic

• sickle cell anemia

• tay-sachs

• PKU
