You find a pink geranium in your flowerbed of red geraniums. Seeds from self fertilization of this plant produce ¼ red plants, ½ pink plants, and ¼ white plants. When considering the visible phenotype, which explanation is most likely?

#Unit 8. Inheritance Biology
  1. The soil in which the pink plant was growing was deficient in a critical nutrient.
  2. The pink plant had a new mutation, creating an allele to  which the wild type "red" is incompletely dominant 
  3. The pink plant had a new mutation, creating an allele which is incompletely dominant to red.
  4. The pink plant had a new mutation, creating an allele which is codominant to "red".
