Description:

Genetics is a field of biology that deals in heredity and variation in living things. All living things inherit different traits from their parents . The idea is being used since prehistoric times to improve crops and animals through selective breeding. Modern genetics was set into action with the work of Gregor Mendel from the mid-nineteenth century. The physical basis for heredity as we know now are the units of inheritance called genes.
