But not all genetic observations can be explained and predicted based on Mendelian genetics. These principles form what is known as the system of particulate inheritance by units, or genes. In Biology, heredity is the term used for transmission of the traits from one generation to the next generation. In 1865, Gregor Mendel published his celebrated observations on the hybridization of pea plants. Mendel instead believed that heredity is the result of discrete units of inheritance, and every single unit (or gene) was independent in its actions in an individual’s genome.
