Explanation
In incomplete dominance, neither allele is completely dominant, so the heterozygous genotype shows an intermediate phenotype. When two heterozygotes are crossed, the genotypic and phenotypic ratio of the F2 generation is 1:2:1 — one homozygous dominant, two heterozygous (intermediate), and one homozygous recessive.
