Hydrangea plants have a gene that codes for having flower color or having no flower color.For those plants that do have flower color,the exact color depends on the amount of aluminum in the plant: they are pink or red when little aluminum is present and blue when aluminum is present.Plants take up more aluminum in acidic soils,so a plant with red flowers can be turned into a plant with blue flowers by lowering the pH of the soil.This is an example of ______ inheritance.
