Incomplete Dominance: Incomplete dominance is a genetic situation where neither allele is completely dominant over the other, resulting in an intermediate phenotype in heterozygous individuals.

Incomplete Dominance in 4 O’clock Plant: In the 4 O’clock plant (Mirabilis jalapa), the flower colour exhibits incomplete dominance. When a red-flowered (RR) plant is crossed with a white-flowered (WW) plant, the F1 generation (RW) displays pink flowers, showing an intermediate phenotype between red and white.
