Mendel performed an experiment in which he took a tall plant with round seeds and short plant with wrinkled seeds. In F1 progeny all tall with round seeds were produced. Tallness and roundness were thus dominant traits. When he used these F1 progeny to generate F2 progeny by self-pollination, he found that some F2 progeny, were tall plants with round seeds, while others were short, but had round seeds. Thus Mendel's experiment shows that tall or short traits and round or wrinkled seed traits are independently inherited.
