question

Hydrangea flowers have one gene for flower color. Plants of the same genetic variety have flowers that range in color from blue to pink with the color varying due to the type of soil in which they are grown. Which of the following statement best explains this phenomenon?

category

biology

options

  1. The flower color is a result of genetic drift within the population.
  2. In this case, the environment alters the expression of a trait.
  3. The genes for flower color show polygenic inheritance.
  4. The alleles for flower color are codominant; both traits show depending on the environment.
  5. The flower color is a result of multiple alleles interacting.
  6. The flower color is a result of the plant's age.
  7. The alleles for flower color show incomplete dominance where neither trait is dominant; expression of the genes shows a blending of traits.
  8. The flower color is determined by the type of pollinators in the area.
  9. The flower color is determined by the amount of sunlight the plant receives.
  10. The flower color changes due to genetic mutation over time.
