Mendel

Cards (3)

    • Mendel carried out breeding experiments on plants
    • observed that inheritance of characteristic determined by units that are passed on to offspring unchanged
    • he concluded that hereditary units can be dominant or recessive
  • his work was not significant until after his death because:
    • chromoses and celll division discovered in 1800s
    • chromosomes and Mendel's "units" had similarities
    • his units were found to be genes, located on chromosomes
    • structure of DNA was found in 1953
    • so, function of genes was worked out
    • led to gene theory being developed
