Answer:
The possible genotype of this cross is RW
Explanation:
This question involves a single gene coding for radish color. The allele for red radish (R) is incompletely dominant over the allele for white radish (W), hence, a third intermediate phenotype is formed when they combine (RW).
In this cross, a pure-breeding red radish (RR) is crossed with a pure breeding white radish (WW) to create the F1 offspring. The red radish will produce gametes R while the white radish will produce gametes W, hence, using a punnet square (see attached image), the F1 offspring will have the genotype: RW.
