Al Blop received 800 F2 tulip seeds from N. T. Careful which he planted in a nice warm

(37C), moist place. Of the 800, only 652 germinated, grew and eventually produced

flowers. Careful had told Blop that the parental types were Red flowers/Smooth petal edges

and yellow flowers/ruffled petal edges--Red dominant over yellow and Smooth over

ruffled--so he could expect a 9:3:3:1 ratio in the F2's he was planting. Blop, however, got

the following results:

440 Red/Smooth; 50 Red/ruffled; 147 yellow/Smooth; 15 yellow/ruffled

(2 = 7.82 at 0.5 and 2 =11.35 at 0.1)
