DNA Relatives: Detecting Relatives and Predicting Relationships

The risk of giving birth to babies with genetic defects as a result of marriages between first cousins is no greater than that run by women over 40 who become pregnant, according to two scientists who call for the taboo on first-cousin families to be lifted. Women in their forties are not made to feel guilty about having babies and the same should apply to cousins who want to marry, said Professor Diane Paul of the University of Massachusetts in Boston and Professor Hamish Spencer of the University of Otago in Dunedin, New Zealand. Although first-cousin marriages are legal in Britain, there have been calls to ban the practice because of reports that it has resulted in a higher-than-average incidence of birth defects in certain immigrant communities where it is common and culturally acceptable. However, Professors Paul and Spencer said that the risk of congenital defects is about 2 per cent higher than average for babies born to first-cousin marriages — with the infant mortality about 4. First-cousin marriages were once quite common in Europe, especially among the elite — Charles Darwin married his first cousin Emma Wedgwood — but that changed in the late 19th-century as people, especially women, became more socially mobile and the risks became more evident. The stigma attached to first-cousin marriages was supported by early studies into human genetics suggesting that “recessive” versions of a gene which are not expressed unless there are two of them, one from each parent are more likely to be expressed in the children of genetically related parents, as well as more likely to be defective.

The study also has implications for population growth in a world that’s becoming more and more urbanized. In Iceland, the dramatic demographic shift from a rural society to a highly urbanized one could slow population growth as individuals mingle with a bigger pool of distantly related mates and therefore have fewer kids. A similar urban shift is happening across the globe.
