Backbone of genetics testing
Mendel studied pea plants and the traits passed down from generation to generation. For example Mendel figured out that the traits of offspring were from both parents not just one or the other.
Scientists Reactions of Mendel's Studies
Mendel had published his work and it wasn't read for quite some time, even after his death. Thirty-five years after Mendel's death three scientists found his books and this jump-started the progress of genetics testing. Genetics Scientists even today refer to Mendel's work.
After the rediscovery of Mendel's work, the conclusions made by him were named Mendel's Laws. These Laws were always referred to by genetics scientists and were the backbone of genetics testing.
