  • Mendel
    • Pea plants- noted how characterisitcs in plants were passed on from one generation to the next
    • Showed that the height of characteristics in pea plants was determined by separately inherited "hereditary units" passed on from each parent. The ratios of tall and dwarf plants in the offspring showed that the unit for tall plants, T, was dominant over the unit for dwarf plants, t.
    • Charcteristics in plants are determined by "hereditary units"
    • Hereditary units are passed on from both parents, one unit from each parent
      • Charcteristics in plants are determined by "hereditary units"
    • Hereditary units can be dominant or recessive- if an individual has both dominant and the recessive unit for a characteristic, the dominant characteristic will be expressed
      • Hereditary units are passed on from both parents, one unit from each parent
