Mendel's Principles

                     Principle of dominance :
                                                            For each trait in the garden   pea, one orm of the trait
                                                            was always dominant over the other. 

 
                         Principle of segregation : 
                                                            The members of an allele pair separate 
                                                             into different gamets.

 
                        Principle of independent assortment : 
                                                           Alleles for different traits behave 
                                                           independently as they assort into the gamets.
