Question

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

Explanation:

• Polygenic inheritance means that a trait is controlled by multiple genes. Eye color (a mix of blue, green, and brown) is a polygenic trait as it is influenced by several genes.
• A cow with red and white dominant coloring shows codominance.
• A plant with pink flowers from red - and white - flowered parents shows incomplete dominance.
• A plant with green seeds from yellow - and green - seeded parents may show simple Mendelian inheritance (if green is dominant).

Answer:

a mix of blue, green, and brown eye colors
