Due to the cross between TTRr × ttrr the resultant progenies showed how many percent plants tall, red flowered :
A
50%
B
75%
C

D
100%
Detailed Solution
Gametes of TTRr: TR and Tr (each 1/2). Gametes of ttrr: tr only.
Offspring: TtRr (tall, red) and Ttrr (tall, white) in equal numbers.
All are tall (Tt), and half are red (Rr).
So 50% of the plants are tall and red flowered.
