Which of these are examples of polygenic traits? a) blood type in humans and birth weight in calves b) birth weight in calves and eye color in humans c) eye color in humans and blood type in humans d) flower color in snapdragons and birth weight in calves

B

Explanation:

Because its b because polygenic traits are things about us.  Birth weight eye color hair color and skin color are all YOUR traits.  Your blood type has nothing to do with you outside traits

B. birth weight in calves and eye color in humans.

Explanation:

In polygenic traits = traits are affected by multiple genes.  Examples are eye, skin, and hair color, birth weight.  

Blood type is an example of multiple alleles and flower color is an example of incomplete dominance.
