WebThe monohybrid phenotypic ratio of 3:1 was the important clue for Mendel to crack the law of segregation. When he crossed the two pea plants in a scientific manner, the result … WebSolution Verified by Toppr Mendel conducted the experiments using Pisum sativum or pea plant. He selected homozygous tall (TT) and dwarf (tt) pea plants. He crossed the tall pea plant with the dwarf pea plant. It was observed that the F 1 generation are all tall plants.
