incomplete dominance. A heterozygous condition in which both alleles at a gene locus are partially expressed and which often produces an intermediate phenotype.
(google)
or
when the phenotype of the heterozygous phenotype is distinct from and often intermediate to the phenotypes of the homozygous phenotypes.
(my class book)
so, the snapdragon flower's color is homozygous for red or white
Well incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. And a example of this is a snap-dragon flower that is pink from cross pollination between a red and a white flower when neither the red or white flower are dominant.
