Since the F1 generation shows both white and red dots, it is a case of codominance.
In codominance, both characters are expressed independently , just like AB blood group.
Let Red dots genotype be RR (assuming it is dominant) and white dots plant rr
Crossing the two purelines gives us F1 hybrid Rr showinbg red and white dots.
the gametes produced by F1 will be R and r
therefore the progeny will be
RR, Rr Rr and rr where Rr is red and white dots therefore out of 4plants, 2 plants show both red and white dots so the fraction will be ½
