Non-Mendelian Genetics

Incomplete Dominance Incomplete dominance: occurs in cases in which one allele is not completely dominant over another.

Codominance Codominance: both alleles contribute to the phenotype. Ex: Chickens Either black, white, or speckled black and white.

Multiple Alleles Genes that have more than two alleles. The individual can still only have two alleles. Ex: coat color in rabbits.

Rabbit Furs cc CC, Ccch, CCh, Cc chc or chch cchch, cchcch, or cchc

Polygenic Traits Polygenic traits: traits controlled by two or more genes. Ex. Skin color

Applying Mendel’s Principles The common fruit fly: Drosophilia melanogaster. Small, easy to keep in the laboratory, and produce large numbers of offspring in a short amount of time. Mendel’s principles apply to all organisms.

Genetics and the Environment Characteristics are determined by interaction between genes and the environment.
