Question: More than a dozen recessive illnesses that are very rare in most of the world are fairly common among the Bedouin people who live in the Negev Desert area of Israel. More than 65% of Bedouin marry their first or second cousins. This practice helped the group to survive a nomadic existence in the harsh enviroment in the past. Recently, two physicians and a geneticist set up a service that enables people wishing to marry to take genetic tests to learn if they are carriers for the same diseases. Prenatal testing has also been introduced to provide the option of terminating pregnancies that would otherwise lead to the births of children who would die of a recessive disorder in early childhood. Discuss the pros and cons of introducing genetic testing in this community. Should medical science interfere with a society's long-held cultural practices?
