Answer:

25% red flowered

25% white flowered

50% pink flowered

Explanation:

Let the red flower color be represented by RR, the white color by rr.

When RR was crossed with rr, the offspring had pink flowers;

RR   x   rr = Rr, Rr, Rr, Rr (Pink color)

Crossing Rr with another Rr

Rr   x   Rr  = RR, Rr, Rr, rr

RR = red

Rr = pink

rr = white

Hence, if a pink flowered plant is crossed with another pink flowered plant, 25% of their offspring will be red, 25% will be white and 50% will be pink.
