Deism (from Latin: deus = God) refers to the eighteenth-century movement in modern Christianity which taught that reasonârather than revelationâshould form the basis of religion.
Inheritance in man conforms to the same genetic principles, which govern inheritance in other animals and in plants. About 200 traits are transmitted from generation to generation in humans.These are called hereditary traits. These include dominant as well as recessive traits.Many human traits are transmitted in a simple Mendelian manner, while many others follow a non-Mendelian pattern shown when there is co-dominance, polygenes and sex-linked genes.hese are called hereditary traits.

A recessive trait is a trait caused by a recessive gene, which means that someone must inherit two copies of the gene for the trait to manifest. By contrast, a dominant trait only requires one copy of the gene. The concept of dominant and recessive traits in genetics was put forward by Gregor Mendel, a 19th century scientist who is often regarded as the father of genetics, thanks to his extensive work in the field.
