1. Unit 8: Mendelian Genetics 8.4 Incomplete Dominance

2. When an allele is either dominant or recessive.
Complete Dominance

3. Incomplete Dominance
When an offspring’s phenotype is a blend of the two parents.
It is like mixing paints, one color does not dominate the other
Examples:
If you take a red flower and a white flower and you breed them, you get a blending of the two colors and get a pink flower.
Hair color

4. Using a Punnett Square for Incomplete Dominance
Use only capital letters because there are no real dominant/recessive traits
Place the two traits onto the Punnett square, the same as you have before.
Cross the traits in the square

5. A cross between a white mouse and a black mouse create grey offspring.
a. parent genotype
b. offspring genotype
c. offspring phenotype
