Mendel s Discoverie 1857 Mendel began breeding garden peas in the garden of the monastary to study inheritance Used hybridization , which is the mating of two contrasting organisms, to study how characters are inherited Observed that offspring inherited characteristics from their parents on a 3:1 ratio He concluded that: 1. There are different versions of genes (called alleles ) 2. For each character, offspring inherits one allele from each parent 3. Two alleles are always present, but only one ( dominant ) is visible in the offspring s appearance 4. Alleles segregate during gamete production 5. The allele for each character is inherited independently These discoveries follow the rules of probability T
