Prenatal diagnosis is the procedure of diagnosing fetal abnormalities or genetic disorders, as well offer expecting parents with information and the chance to alter pregnancy management and postnatal care. Preimplantation diagnosis is a method used prior to recognize genetic defects within embryos fertilised through in vitro fertilization to avoid some diseases or disorders from being passed on the child. There are a variety of genetic techniques which plays a major role in prenatal and pre implantation genetic diagnosis. This review paper explains the role of genetic techniques in both prenatal and pre implantation diagnosis along with other available noninvasive and invasive techniques.
