Biostatistics tools. Gregor Mendel started the genetics studies investigating genetics segregation patterns in families of peas and used statistics to explain the collected data. In the early 1900s, after the rediscovery of Mendel's Mendelian inheritance work, there were gaps in understanding between genetics and evolutionary Darwinism. Francis Galton tried to expand Mendel’s discoveries with human data and proposed a different model with fractions of the heredity coming from each ancestral composing a infinite series. He called this the theory of "Law of Ancestral Heredity". His ideas were strong disagreed by William Bateson, who followed Mendel's conclusions, that genetic inheritance were exclusively
Genetics inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding. The modern science of genetics, seeking to understand this process, began with the work of the Augustinian friar Gregor Mendel in the mid-19th century. Prior to Mendel, Imre Festetics, a Hungarian noble, who lived in Kőszeg before Mendel, was the first who used the word "genetics." He described several rules of genetic inheritance in his work "The genetic law of the Nature" (Die genetische Gesätze der Natur, 1819). His second law is the same as what Mendel published. In his
