incomplete dominance
codominance
What type of inheritance pattern do two alleles for a gene follow if their traits blend together on the offspring?
Incomplete dominance
Codominance
____ is an inheritance pattern that results in offspring that are a MIXTURE of the two traits of its parents, like yellow and blue flowers making green offspring.
incomplete dominance.
codominance

The hair form gene shows incomplete dominance. If your genotype is SS, you will have straight hair. If your genotype is CC, you will have curly hair. If your genotype is SC, you will have wavy hair. Mr. and Mrs. Anderson both have wavy hair (SC). What percentage of their children will also have wavy hair (SC)?
25%
50%
75%
100%

What is the key difference between incomplete dominance and codominance?
Incomplete dominance results in a blend of traits, while codominance results in both traits being expressed
Incomplete dominance results in one trait being completely dominant, while codominance results in a blend
Incomplete dominance results in both traits being expressed, while codominance results in a blend
There is no difference
