In terms of phenotype frequency, what ratio is associated with incomplete dominance?

Incomplete dominance occurs when the phenotype of a heterozygote is distinct and appears as a blend of the two homozygous phenotypes. For example, when red and white flowers are crossed, the resulting offspring may exhibit a pink phenotype rather than fully expressing either color.

In a typical monohybrid cross involving incomplete dominance (where one trait does not completely dominate over another), you would start with pure-breeding individuals for both traits. When these individuals are crossed, the F1 generation will exhibit a blended phenotype. If these F1 individuals are then crossed with each other, the F2 generation exhibits a specific phenotypic ratio.

The resulting phenotypes from this cross can be classified as:

• The dominant phenotype (homozygous dominant)

• The intermediate phenotype (heterozygous)

• The recessive phenotype (homozygous recessive)

In terms of frequency, there will be one homozygous dominant phenotype, two heterozygous phenotypes exhibiting the blended trait, and one homozygous recessive phenotype. This results in a 1:2:1 ratio of the phenotypes in the offspring, which highlights the unique outcome of incomplete dominance where the intermediate condition is evident in a notable proportion of the progen
