Which represents polygenic inheritance of traits?
a> a cow that has red and white dominant coloring
b> a mix of blue, green, and brown eye colors
c> a plant that has pink flowers produced from a plant that has red flowers and a plant that has white flowers
d> a plant that has green seeds produced from a plant that has yellow seeds and a plant that has green seeds

The correct answer is a mix of blue, green, and brown eye colors.
Polygenic inheritance is a pattern of inheritance when the trait is not controlled by one gene, but by multiple genes that each make a small contribution to the overall outcome. In this case, the trait of the eye color is controlled by different genes (for blue, green, and brown eye colors). It becomes hard to distinguish the effect of each individual gene in polygenic inheritance.
