Codominance and Incomplete Dominance

Codominance: both traits are expressed (in animals) Ex: human blood type AB makes both anitgen A and antigen B

Ex: Cattle RR – red (rusty brown) WW- white RW- Roan (red and white) *Not Pink P1 = WW x RW

Incomplete dominance: one does not. completely hide the other, Incomplete dominance: one does not completely hide the other, traits blend (in plants) Ex: flowers P1 = RR x RW RR - red WW - white RW - pink

Four o’clocks are flowers that exhibit incomplete dominance
