                                                           Mendel studied genetics by doing controlled

                     Let us learn some vocabulary


         Heredity
         the passing of traits from parents to offspring.                  Self-pollination






















                                                            When a true-breeding plant
                                                            self-pollinates, it always
                                                            produces offspring with traits
                                                            that match the parent.
        Let’s Begin



                                                           Mendel cross-pollinated pea plants himself and
        Early Ideas About Heredity                         recorded the traits that appeared.

        Heredity is the passing of traits
        from parents to offspring.



        Gregor Mendel is known as
        the father of genetics—the study
        of how traits are passed from                                   2
        parents to offspring.                                                                       1
