    • Gregor Mendel, father of Genetics, developed the law of inheritance
    • An experiment was conducted on garden peas 
    • 7 different phenotypes or traits were considered
    • A cross was made between two plants: one dominant and one recessive
    • The traits exhibited by the dominant and recessive plants are as follows:
      Character Dominant Recessive
      Seed shape Smooth Wrinkled
      Seed color Yellow Green
      Flower color Purple White
      Pod shape Inflated Constricted
      Pod color Green Yellow
      Flower position Axial Terminal
      Stem length Tall Dwarf

    • Gene is the hereditary unit
    • Gene can have different versions called alleles
    • The alleles can be dominant or recessive
    • The presence of a dominant allele will mask the presence of a recessive allele

    Mendel’s idea that the pair of alleles of each parent separate and only one allele from each parent is passed to an offspring is explained by:

    • Law of segregation is the second law of inheritance
    • Law of inheritance is based on the following:
    1. Gene can exist in various versions called alleles
    2. During meiosis, separation of allelic pair occurs providing single allele to each gamete
    3. Organisms inherit two alleles for each phenotype
    4. In an allele pair, one is dominant while other is recessive
