Incomplete dominance

Answer: Haven't done this for a while but I think I know what it is.
The red flower (the one on the left) will be RR.
The white flower (The one on the right) will be rr.
And finally, the pink flower is going to be Rr.
RR is Dominant.
rr is Recessive
Rr will be Incomplete Dominance
Hope that helps you!!
