Deoxyribonucleic acid profiling or just DNA profiling is technology that can be used to identify individuals by their DNA. The discovery of DNA profiling was in September 1984 by Alec Jeffrey, a geneticists from the University of Leicester in England, he was focusing to resolve immigration and paternity disputes. DNA profiling, known as STR analysis is very sensitive and only requires a few skin cells e.g. a line of hair, a drop of blood, a drop of saliva or the most common way, which is a fingerprint
genes for health purposes or in some cases changing their appearance. The first ever designer baby was Adam Nash. They used what is called the pre-implantation process which is Preimplantation genetic diagnosis (PGD or PDGS) refers to the genetic profiling of embryos prior to implantation, and sometimes even of oocytes prior to fertilization.
