In Mendel's monohybrid crosses, he observed a phenotypic ratio of 3:1 in the offspring. This occurs when crossing two homozygous parents for a single trait, leading to three dominant phenotype individuals for every one recessive phenotype individual in the F2 generation. Therefore, the correct answer is 3:1.
