The history of the field of genetics includes a number of major discoveries made by scientists, some of whom became very famous and others who have almost been forgotten.
The study of genetics began with the discoveries of Mendel, who studied pea plants and identified the basic laws of inheritance.
His work identified that many genes are inherited in a
manner, as shown in the Punnett square above. This work was supplemented by the determination that the molecule responsible for inheritance is DNA, which was proven by Hershey and Chase using bacteriophages. This experiment determined that DNA was the inheritance molecule by labeling protein with
