The research, conducted by the BBC and broadcast to a shocked nation on Tuesday, found that at least 55% of the community was married to a first cousin. This is thought to be linked to the probability that a British Pakistani family is at least 13 times more likely than the general population to have children with recessive genetic disorders.” The lower percentages might be because it is difficult to get the chosen family member to the country, or because health education is better in the West.
