Incomplete dominance is a type of inheritance where one allele for a trait is not fully dominant over the other allele so a blended phenotype may result.
In wheat kernels, color is determined by two genes. Each of these two genes can have two alleles (A1, A2, B1, B2). If four A1 or B1 are present, kernel color will be red. If four A2 or B2 alleles are present, kernel color will be white. But we also see three blended kernel colors - dark pink, medium pink, and light pink depending on the mix of type 1 and type 2 alleles.
Therefore, yes, wheat kernel color is an example of incomplete dominance.
