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
e. 0% white
When crossing two pink flowering fruitloop plants (WR), the possible genotypes in the F2 generation are WW, WR, and RR.
When using a Punnett square to set up the cross between two WR individuals:
W R
__________
W | WW | WR |
__________
R | WR | RR |
The possible offspring genotypes are WW, WR, and RR.
Since white flowers (WW) only arise when both alleles are white, there will be no white flowered offspring in the F2 generation of the cross between two pink flowering fruitloop plants.
