    ✅Explanation:
    Gregor Mendel, the father of modern genetics, chose pea plants (Pisum sativum) for his groundbreaking experiments.

    🔑Key Points:
    -Johann Mendel was born on 20 July 1822 Heinzendorf bei Odrau, Silesia, Austrian Empire.
    -Mendel's pea plant experiments conducted between 1856 and 1863 established many of the rules of heredity, now referred to as the laws of Mendelian inheritance.

    ✏Mendel worked with seven characteristics of pea plants:
    -​Plant height, pod shape and colour, seed shape and colour, and flower position and colour.

    🛑Additional Information:

    ✏The reason for the selection of pea plants for the genetic experiments are:
    -They have excellent disease resistance and have an optimal rate of survival.
    -The generation time of pea plants is less.
    -Easy to obtain pure breed plant through self-fertilization.
    -The flowers of pea plants are hermaphrodite, i.e flowers have bisexual characteristics.
    -Easy to grow in the garden.
