        For parental (P) crosses, Mendel chose true-breeding plants that exhibited the two forms of
        a characteristic. For example, he crossed a true-breeding tall plant and a true-breeding short
        plant. In this investigation, assume that the parental crosses are also true-breeding plants.
        Count the number of offspring exhibiting each trait in each generation and complete the data
        table. Then answer the questions based on your observations.
