Non Mendelian Genetics

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

• heterozygotes

• multiple alleles

• epistatic

• polygenic

In mice, the homozygous mice are black and white. The heterozygous mice are gray. What pattern of inheritance is expressed in fur color in mice?

• complete dominance and recessiveness
• co-dominance
• incomplete dominance
• pleiotropy
