• 25 %

• 50%

• 75%

If blue and red true-breeding flowers are mated and result is all purple offspring, what inheritance pattern would this be indicative of?

• Codominance

• Dominance

• Incomplete dominance

• Multiple Alleles

AB blood type is an example of what type of inheritance? Both alleles show in the phenotype

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

This is when a trait is controlled by more than one gene.

• Multiple alleles
• Polygenetic inheritance
