The Ethics of Genetics Screening

Ignoring some of the aesthetic issues, Dr. Daniel Eisenberg provides a very interesting look into the Jewish ethical perspective on issues related to screening for Tay-Sachs disease

Genetic screening for recessive traits is a great boon to the Jewish community (and the rest of the world).
