Why Include the Mother in a Paternity Test?

Though mother is not actually required in a paternity test but her DNA sample can actually play a vital role in deciding the result of a paternity test. The inclusion of the DNA sample of child’s mother not only increases the validity of the test but it also ensures that her biological child has been sampled properly.

It is a general knowledge that a child’s DNA is composed of the equal amount of genetic markers of his/her biological mother and father. If a mother is not included in a paternity test, the chances of false inclusion of an alleged father increases. False inclusion happens when an alleged father is tested and gets falsely included as the biological father of the child when he should actually be excluded.

50/ 50 

When a mother’s DNA is included in a paternity test, half of the alleles of a child’s DNA are matched with that of mother’s and hence only remaining alleles i.e. half of the alleles are to be tested against that of an alleged father. When the maternal alleles have already been accounted for, and remaining alleles are tested for paternity, the chances of false inclusion becomes 0. So, if mother’s DNA sample is not collected for a paternity test, all the alleles of the child are compared with that of an alleged father which leads to decrement in paternity index at each genetic marker and the overall CPI as well.
