red, white, and pink red and white pink and red pink and white
I gave my students this multiple choice question: A red flowered plant (RR) is crossed with a white flowered plant (WW) and produces plants with pink flowers (RW). If two pink flowered plants are crossed, what color offspring could be produced?

Only one answer is correct among these 4 choices:
- red, white, and pink
- red and white
- pink and red
- pink and white

Could you tell me which one is correct?

red, white, and pink
