These and several related questions are dealt with, scientifically, in a branch of biology known as Genetics. This subject deals with the inheritance, as well as the variation of characters from parents to offspring. Inheritance is the process by which characters are passed on from parent to progeny; it is the basis of heredity.

there can be evolution without natural selection, but there cannot be evolution without variation. In this section, the fundamental principles of heredity and variation that are necessary before a complete understanding of evolution is possible are described. A basic understanding of genetics is assumed. INDIVIDUALS AND
