<span>The answer is  A -The red geranium is heterozygous for red flowers (Rr).
We know that the red flower, to be red needs to have at least a dominant allele, so it could be either Rr or RR. 
Let's try both scenarios.
If the white</span><span> geranium (rr) is being crossed with RR, all the offspring would be red with genotype: Rr.
On the other hand, if the flower is Rr and it's being crossed with rr, that would result in </span><span>half of the new generation plants having red flowers and the other half white flowers.</span>
