In routine parentage tests, trio analyses (father-mother-child) are preferred. Under certain circumstances, laboratories may have to perform duo analysis (without mother/father). However, duo analyses increase the risk of false inclusions. This paper aimed to evaluate the false inclusion risks of duo analyses in the Turkish population from the point of forensic applications and the Turkish judicial system. Children from 400 previously analysed cases were compared separately with fathers and mothers of other cases by using a computer programme. From the total 345,006 comparisons, in 16 comparisons, no Short Tandem Repeat (STR) mismatch was observed at 15 STR loci between the child and an unrelated parent. In other words, duo tests provided a coincidental second mother or father to 16 children. In almost all of these cases, the probabilities of paternity estimation values are greater than Turkish Judicial System's parentage acceptance limit, which is 99.73%. According to results, we suggested that trio cases should be performed as much as possible and the parentage acceptance limit, which is 99.73%, should be re-evaluated by a law maker's commission to prevent false inclusion parentage cases in Turkey.
