Heredity particulate inheritance of genes can be attributed to the Moravian monk Gregor Mendel who published his work on pea plants in 1865. However, his work was not widely known and was rediscovered in 1901. It was initially assumed that Mendelian inheritance only accounted for large (qualitative) differences, such as those seen by Mendel in his pea plants—and the idea of additive effect of (quantitative) genes was not realised until R. A. Fisher's (1918) paper, "The Correlation Between Relatives on the Supposition of Mendelian Inheritance" Mendel's overall contribution gave scientists a useful overview that traits were inheritable.

Christian Carl André Christian Carl André Christian Carl André (1763-1831) was a leading 19th century European natural scientist, publisher, economist and educator. He was among the pioneers in the study of heredity whose vision paved the way for the research of Gregor Mendel, the founder of modern genetics. Christian Carl André was born on 20 March 1763 in the German town of Hildburghausen. He studied at the University of Jena, and worked as a teacher in Eisenach and at the Schnepfenthal Salzmann School in Gotha.
