PRINCIPLE OF GENETICS
It is common observation that seeds of mango trees grow into mango plants, does give birth to puppies and not into the young ones of any other animal. Humans give birth to human beings. The tendency of offspring to inherit parental characteristics is termed ‘heredity’ and the science of heredity and variation is called ‘Genetics’. Genetics also seeks to answer questions like why two offspring of same parents look different, why are some people dark and others light skinned etc. In other words, why is there variation among individuals of the same kind.
