2
Q

Mutually exclusive events
3
Q
What are the 4 apparent deviations from Mendel’s laws?
A

4
Q
What are polymorphic genes?
A
Genes with many different alleles but each individual can only have two of them
5
Q
What is incomplete dominance?
A
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
6
Q
What is codominance?
A
When both phenotypes exist side by side within the organism
7
Q
What are polygenic traits?
A
Traits with a phenotype controlled by many genes that have an additive effect. These traits display normal distribution
