• • Demonstrated the traits are passed from parents to offspring forming specific patterns over generations of crossbreeding
• • He accurately deduced the basic principles of inheritance by studying several inheritable traits in the same pea plant species using precise experimentation and careful observation over many years
• • He used monohybrid crosses to discover the dominance relationships of traits in pea plants 
• p - plant generation – homozygous dominant x homozygous recessive

  F1 first filial generation – heterozygous offspring

  F2 second filial generation
• • In a standard monohybrid cross, homozygous parents are crossed to produce heterozygous offspring in the F1 generation
• • These heterozygous offspring are then crossed with each other to produce the f2 generation
• • The phenotypic ratios in offspring in the f1 and f2 generations indicate which phenotypes are dominant or recessive
