Answer:

Its 4 red: 0 white

Explanation:

look at a RrRr punnet square, then it shows the ratio.

the square shows that all the plants will be red because if a trait is recessive, it needs to be shown in both parents for the offspring to have it. All offspring will carry this trait, but it will not show.
