Non- Mendelian Genetics

A single gene has 3 or more alternative forms. These are called

• heterozygotes

• multiple alleles

• epistatic

• polygenic

If this image were real, it would represent what type of inheritance?

• incomplete dominance
• codominance
• polygenic inheritance
• compete dominance
