Answer

Yes, the observed results would be fairly close to what we would expect from this cross. If one parent were $RR$, then all offspring would be heterozygous ($Rr$), and the offspring would all have smooth seeds. This means that one parent has to be heterozygous ($Rr$) while the other must be homozygous recessive ($rr$).
