In a certain plant, red flowers $(R)$ are dominant to white flowers $(r)$ and tallness $(T)$ is dominant to dwarfness $(t)$. A heterozygous plant $(RrTt)$ is backcrossed with a double recessive plant $(rrtt)$. If the gene loci for colour and size and situated very close together on the same chromosome, the expected percentage of offsprings could be approximately

tall red

tall white

dwarf red

dwarf white
