Gregor Mendel pod shape, unripe pod color, flower location, and plant height. He first focused on seed shape, which was either angular or round. Between 1856 and 1863 Mendel cultivated and tested some 28,000 plants, the majority of which were pea plants ("Pisum sativum"). This study showed that, when true-breeding different varieties were crossed to each other (e.g., tall plants fertilized by short plants), in the second generation, one in four pea plants had purebred recessive traits, two out of four were hybrids, and one out of four were purebred dominant. His experiments led him to make two generalizations, the Law of

Theoretical and Applied Genetics Theoretical and Applied Genetics is a peer-reviewed scientific journal published by Springer Science+Business Media. The journal publishes articles in the fields of plant genetics, genomics, and biotechnology. It was established in 1929 as "Der Züchter", which name was changed to the current one in 1968. Previous editors include H. Stubbe (1946–1976) and H. F. Linskens (1977–1987). The journal publishes
