Father of Genetics. Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
DNA was first discovered back in 1869 by Johann Friedrich Miescher. The fundamental structure of DNA was discovered by James Watson and Francis Crick, although many people believe that Rosalind Franklin also played a large role in their research.
