Pre-Implantation Genetic Diagnosis, commonly abbreviated to as PGD is the act of obtaining and analysing the genetic profile of an embryo(s) before selecting a suitable set with the right genetic profile which will then be implanted in to a uterus to allow for the selected embryo(s) to develop. PGD involves the genetic screening of embryos which are at a high risk of obtaining a genetic disorder such as cystic fibrosis, Huntington’s disease (HD) and Down syndrome etc. The genetic screening of the embryos allows for the identification then elimination of embryos containing the alleles of the genetic disorder therefore reducing the high probability of the embryo that is implanted containing the genetic disorder. This is an early stage of prenatal
