When red snapdragons are crossed with white snapdragons, the offspring produce pink flowers. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

When red cows are crossed with white cow, the offspring have a mix of red hair and white hair. These cows are called roan. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

Human eye color is controlled by three different genes, and affected by a dozen more. This is an example of:

• complete dominance

• incomplete dominance

• codominance

• polygenic inheritance

• multiple alleles

There are three common alleles for the gene that controls blood type. These are A,B, and O. Their Dominant/recessive relationship is: 

• A and O are codominant and B is recessive
• O is dominant and A and B are corecessive
• A and B are codominant and both are dominant to O
• B and O are codominant and both are dominant over A

A father that has blood type O is crossed with a blood type O mother. What will be the genotype of the offspring?

• 50% AB; 50% OO
• 25% AB,  25% AO, 25% BO, 25% OO
• 25% AA, 25% BB, 25% AB, 25% OO
• 100% OO

• 25% AA, 25% BB, 25% AB, 25% OO
