Genetic combinations of wheat kernel pigment with different genotypes and their corresponding color intensities.

The diagram illustrates the combinations of alleles (A, B, C) and their effects on pigment intensity in wheat kernels, showing a range of colors from dark red to white.

Three genes that make reddish pigment in wheat kernels are called A, B, and C. Each gene comes in two alleles: one capital-letter allele that makes pigment and one lowercase allele that does not.

The alleles have additive effects: - The aa genotype contributes no pigment. - The Aa genotype contributes some pigment. - The AA genotype contributes more pigment (twice as much as Aa). The same applies to the B and C genes.
