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
<em>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.</em>
