In incomplete dominance, the heterozygous phenotype is intermediate between the two homozygous phenotypes, leading to a 1:2:1 phenotypic ratio in the offspring of two heterozygotes. The genotypic ratio is also 1:2:1, representing one homozygous dominant, two heterozygous, and one homozygous recessive.
