Quantitative Traits Experiments
Walter S Sutton did some experiments on quantitative traits in broad beans. -
Introduction of "Genetics"
The first time to introduce the term "Genetics" by William Bateson. -
chromosome theory of heredity
Thomas Hunt Morgan came up with a theory about the l
sex-linked inheritance. It was applied on the first mutattion of fruit fly, Drosophila and white eye. -
Relation between genes and enzymes.
George Beadle and Edward Tatum managed to reveal the relation between the genes and enzymes. They found that genes are responsible for producing particular genes. -
Ration between A C T G
Erwin Chargaff found that Adenine has the same amount as Thymine and Guanine has the same amount as Cytosine in DNA samples. -
DNA and heredity
Alfred Hershey and Martha Chase discovered that DNA are the molecules that are responsible for heredity.
