  • MENDEL'S EXPERIMENTS - Indiana University Bloomington

    In Mendel's experiment, the parent plants were homozygous (eg, T T or t t ) for the measured trait, because they could produce only plants with that trait, if they were self-pollinated. That is, they bred true. Also, 1/4 of the F2 (2nd generation) plants in Mendel's experiments bred true as tall plants and 1/4 bred true as short plants.
