No two individuals are absolutely alike in a population. This is because of genetic combinations.
1) During development of a living body, genetic strands called DNA are formed.
2) These are inheritted from the parents. The DNA copies are generated during reproduction.
3) These DNA copies can be similar, but they can never be identical.
4) This portrays the fact that, a child bears some traits of his/her parents, but can never be identical to that of neither the father nor the mother.
