Abstract

Egyptian society suffers from increasing in the number of divorce cases which leads to different problems. One of them is the children’s street that is a result of paternity issues. Paternity cases are caused due to huge problems between married couples because women may be entering a sexual partner in her life so the child will be not the son of her husband. This study discusses the techniques that are used in paternity cases in order to detect the biological father and prove which technique is more accurate compared to other techniques. Blood groups were the first approach that was used to detect whether the case is inclusion or exclusion. The most common and accurate technique is a short tandem repeat. This technique depends on 16 short tandem repeat loci founded on the chromosomes. It also depends on the length of each locus. This study discusses 6 samples concerned with 2 paternity cases while in one case concerned father, mother and two children.
