What is the expected phenotypic ratio of offspring from a monohybrid cross between two heterozygous parents?

💡 Explanation:

A monohybrid cross between two heterozygous parents (e.g., Bb x Bb) results in offspring with a genotypic ratio of 1 (BB): 2 (Bb): 1 (bb). Assuming B is dominant, the offspring will exhibit two phenotypes: the dominant trait (BB and Bb) and the recessive trait (bb). This combination yields the classic Mendelian phenotypic ratio of 3:1.
