    • Gregor Mendel studied the concept of inheritance by experimenting on garden peas
    • The pea plant has 14 chromosomes
    • The DNA of the pea plant codes for 7 genes which are present in a pair of chromosomes
    • The 7 pairs of contrasting characters include:
    Character Dominant Recessive
    Seed color Yellow Green
    Seed shape Round Wrinkled
    Pod shape Inflated Constricted
    Pod color Green Yellow
    Flower color Purple White
    Flower position Axial Terminal
    Stem height Tall Short

    • Mendel used true breeding plants
    • The parent generation were homozygous with contrasting characters
    • The contrasting characters of the parents were dominant and recessive
