In incomplete dominance, the heterozygous genotype (RW) expresses a phenotype that is a blend of the two homozygous phenotypes.
In this scenario:
- The red flowered plant has the genotype RR.
- The white flowered plant has the genotype WW.
When these two plants breed, all offspring will be heterozygous (RW), because:
RR (red) x WW (white) → All RW (pink)
Thus, 100% of the offspring will have pink flowers.
The correct answer is **100%**.
