Incomplete Dominance Sometimes, depending on the way the different proteins from each allele interact genes don’t completely dominate the alternate allele Mendel, studying four o’clocks, gave up genetic research because of this fact.

Example Some species of flowers when you cross a red petal with a white petal produce a pink petal. Red = R White=R’ Possible genotypes: Red = RR White = R’R’ Pink = RR’

Cross an incompletely dominant pink flower with a red flower. RR R’ RR’ 5/6. Red = 2/4 White = 0/4 Pink = 2/4 1. Dom = Red & White Blend= Pink Hybrid 2. R = red R’= white RR’= pink 3. Mom = RR’ Dad = RR 4. R R’ R R
