Incomplete dominance is shown in the fruitloop flower, WW are white, RR are red and WR are pink.
Use scratch paper to set up a Punnett square for a cross of two of the F1 generation (pink flowers).
What is the percentage of white flowered offspring in the F2 generation of the cross between two pink flowering fruitloop plants?
a
100% white
b
75% white
c
50% white
d
25% white
e
0% white
The correct answer is d) 25% white.
Punnett square for the cross between two pink flowering fruitloop plants (WR x WR):
W R
----------------
W | WW | WR |
----------------
W | WR | RR |
In the F2 generation, there will be 25% white flowered offspring, as shown in the Punnett square.
