Question 1

What are 5 inheritiance patterns that are more complex than simple Mendelian Genetics?

Answer 1

1. Simple genes with more than 2 alleles
2. Incomplete Dominance
3. Co-Dominance
4. Polygenic Inheritance
5. Effect of Envrionment on Phenotype

Question 2

Complete Dominance

Answer 2

An allele is fully dominant over another.

Question 3

Incomplete Dominance

Answer 3

Neither allele is completely dominant.

Question 4

Codominance

Answer 4

Two alleles affect the phenotype in separate, indistinguishable ways.

E.G. In Blood Cells

Question 5

Is a dominant allele more common than a recessive allele?

Answer 5

Not always.

Question 6

Polygenic Inheritance

Answer 6

An additive effect of two or more genes on a single phenotypic character.

E.G. Skin color
