1 Codominance and Incomplete Dominance

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

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

4

5 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

6 Four o’clocks are flowers that exhibit incomplete dominance

Exceptions to Mendel’s laws. 1) Incomplete dominance Some alleles are not completely dominant and the offspring will have a “blending” of the parents.

Incomplete or Co-Dominant?!?!. Normally traits have one dominant allele and one recessive allele…. What happens when an allele for a trait isn’t completely.

Beyond Dominant and Recessive Alleles. The whole story... Not all phenotypes are dictated by dominant and recessive alleles (in fact, very few are). Some.
