Mendelian Genetics - Incomplete Doinance & Codomiance Flashcards
1
Q
What is Incomplete Dominance?
A
It occurs when to genes that are equally dominant interact, producing a new phenotype that as intermediate characteristics
Eg. RR (Red Flower) x WW (White Flower) = RW (Pink Flower)
2
Q
What is Codominance?
A
When both genes are expressed at the same time
Eg. RR (Red Bull) x WW (White Cow) = RW (Roan Cow)
3
Q
ABO blood groups
A
An example of CODOMINANCE, and it involves three different alleles (A,B,O)
Any one individual will possess two of the three allelic forms and they will determine blood type
