  • The work of Mendel
    • Gregor Mendel studied how characteristics in plants were passed on from parents to their offspring
    • Mendel's experiments had shown that the height characteristics in pea plants was determined by sepeartley inherited 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.
    • Mendel reached three important conclusions
      • Mendel reached three important conclusions about inheritance in plants
      • Characteristics in plants are determined by inherited units
      • Units are passed on from both parents, one unit from each parent
      • Units can be dominant or recessive- if an individual has both the dominant and the recessive unit for a characteristic, the dominant characteristic will be expressed
