  • Gregor Mendel

    Gregor Mendel
    Experiment:
    He bred garden peas, in which he used to study the inheritance of phenotypes
    He also crossed characteristics to create several generations.
    Contribution:
    His main contributions are the principle of independent assortment and the principle of segregation.
    Some of his minor contributions are the F1 and F2 generations, crosses, and self fertilization.
  • William Bateson and Reginald Punnett

    William Bateson and Reginald Punnett
    Experiment:
    They used 2 characterists and crossed them to get a an expected outcome
    Contribution:
    They are responsible for linked genes and discovering the genotypic ratio.
  • Thomas Hunt Morgan

    Thomas Hunt Morgan
    Experiment:
    He crossed fruit-flys to study genetic recombination
    Contributions:
    His contributions are the chromosomal theory of inheritance, gene mapping, sex linkage, and recombination frequency.
  • Archibald Garrod

    Archibald Garrod
    Experiment:
    He studied inborn errors in the metabolism, like alkaptonurnia.
    Contribution:
    His contributions are transciption and translation.
  • Frederick Griffith

    Frederick Griffith
    Experiment:
    He used a pathogenic bacteria and a non-pathogenic bacteria the pathogenic bateria and injected it into a lab-rat, the lab rat didn't die, but when he added it with the non-pathogenic, it killed the lab rat.
    Contribution:
    His main contribution was the tranforming factor.
  • George Beadle and Edward Tatum

    George Beadle and Edward Tatum
    Experiment:
    They studied Neurospora crassa
    Contribution:
    They clarified the relationship between genes and enezymes.
  • Erwin Chargaff

    Erwin Chargaff
    Experiment:
    He compared the amounts of adenine and thymine.
    Contribution:
    His main contribution was Chargaff's rule, which basically stats the a pairs with t and g pairs with c.
  • Alfred Hershey and Martha Chase

    Alfred Hershey and Martha Chase
    Experiment:
    They used a radioactive marker and marked the DNA and also marked the outside of the phage to see if the DNA, was the heroditary material.
    Contribution:
    Their major contribution was that DNA was infact the heroditary material.
  • Maurice Wilkins and Rosalind Franklin

    Maurice Wilkins and Rosalind Franklin
    Experiment:
    They took x-ray crystallographic photographs of DNA.
    Contribution:
    helped to find DNA structure.
  • James Watson and Francis Crick

    James Watson and Francis Crick
    Experiment:
    They looked at x-ray crystallographic photos of DNA, to help construct a life sized model of the structure of DNA.
    Contribution:
    Their contribution is that they finally determined that DNA is infact a double helix and they also created a model of DNA
  • Marshall Nirenberg

    Marshall Nirenberg
    Experiment:
    He studied the codons for the genetic code of the protein Phenylalnine.
    Contribution:
    He's major contribution was discovering genetic code.
