What is the major advancement in genetic technology?
The major advance in genetic technology has primarily been in the areas of diagnosis and prediction of genetic disorders. We can presently diagnose far more than we can treat. These activities involve genetic screening in which a geneticist attempts to discover the presence or absence of one or more genetic traits or conditions in an individual. There are predominantly four kinds of screening. Neonatal screening is genetically testing newborns for certain disorders and was the first form of genetic screening to be developed. The PKU screen was developed in the 1960’s and is now a standard screen for newborns.
