Mendelian inheritance is the inheritance of biological features that follows the laws proposed by Gregor Johann Mendel in 1865 and 1866 and re-discovered in 1900. It was initially very controversial. When Mendel's theories were integrated with the chromosome theory of inheritance by Thomas Hunt Morgan in 1915, they became the core of classical genetics. Following traits were studied by Mendel in a garden pea plant :
1. Flower colour is purple or white
2. Flower position is axil or terminal
3. Stem length is long or short.
4. Pod shape is inflated or constricted
5. Pod colour is yellow or green
6. Seed shape is round or wrinkled
7. Seed colour is yellow or green
