A cross between two snapdragon varieties- one with red flowers and one with white flowers produces F1 hybrids all with pink flowers .This is an example for
incomplete dominance
In snapdragon, crossing pure red (RR) and pure white (rr) flowered plants produces pink (Rr) flowered plants. In this case the dominant allele ‘R’ is not completely dominant over the recessive allele ‘r’. This phenomenon is called incomplete dominance.
