Genetic make up of a child is related to the genetic constitution of the
parents. Two methods can be used to determine the identity of the
babies as to their parents.
(i) Blood Grouping. In many cases,
matching of blood groups of the baby and the parents can give indication
of their relationship.
(ii) DNA Finger Printing- Comparison of VNTRs or RFLP of the parents provides fool proof method of determining the relationship.
