In a mono-hybrid cross of two heterozygous individuals, the expected phenotypic ratio is 3:1, and the genotypic ratio is 1:2:1.
Phenotypic ratios among the offspring of a mono-hybrid cross of two heterozygous individuals for any trait are typically 3:1. This ratio occurs because one genotype is homozygous dominant, two are heterozygous, and one is homozygous recessive. In terms of genotypic ratios, the ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive.
