Incomplete dominance refers to a genetic situation in which one allele does not completely dominate another allele and therefore results in a new phenotype.
As an example, incomplete dominance is seen in cross-pollination experiments between red and white snapdragon plants. In this monohybrid cross, the allele that produces the red colour (R) is not completely expressed over the allele that produces the white colour (r). The resulting offspring are all pink.
