This concept was discovered by Gregor Mendel and was named as the fundamental laws of inheritance. Through many years as a friar and scientist, Gregor established certain principles through observation and repetition of his experiments with peas.
He could link the findings of his experiments with peas to human traits and characteristics between parents and offspring. Today, he is considered the father of genetics for his contribution to the world of science. Thanks to him, genetics has opened up a whole new realm where benefits to mankind are unprecedented. Diseases that were previously considered incurable are now given a second look with various possibilities for a cure.
