What are the 4 apparent deviations from Mendel’s laws?
- polymorphic genes
- incomplete dominance
- co-dominance
- polygenic traits
What are polymorphic genes?
Genes with many different alleles but each individual can only have two of them
What is incomplete dominance?
When the F1 generation has an intermediate phenotype that appears to be a mix between the parental phenotypes. The F2 generation will include parental phenotypes
What is codominance?
When both phenotypes exist side by side within the organism
What are polygenic traits?
Traits with a phenotype controlled by many genes that have an additive effect. These traits display normal distribution
