【单选题】CharlesDarwin wed his cousinEmma and spawned 10 children, including four brilliant scientists.AlbertEinstein’s second wifeElsa was his first cousin. Queen Victoria said “I do” to hers. So have millions worldwide. In parts of SaudiArabia, 39% of all marriages are between first cousins.
In the U. S., though, the practice bears a stigma of inbreeding just this side of incest. The taboo is not only social hut legislative; 24 states ban the marriage of first cousins: five others allow it only if the couple is unable to bear children.
A、major reason for this ban is the belief that kids of first cousins are tragically susceptible to serious congenital illnesses.
That view may have to change.
A、comprehensive study published recently in the Journal of GeneticCounseling indicates such children run an only slightly higher risk of significant genetic disorders like congenital heart defects — about two percentage points above the average 3% to 4%. Says the study’s lead author, RobinBennett, president-elect of the National Society of GeneticCounselors, which funded the study: “Aside from a thorough medical family history, there is no need to offer any genetic testing on the basis of consanguinity alone”.
Publication of the study will do more than tweak public awareness; it will enlighten doctors who have urged cousin couples not to have children. “Just this week,” saysBennett, “I saw a 23-year-old woman who had had a tubal ligation because her parents were cousins and her doctor told her she shouldn’t have children.”
TheAmerican proscription against cousin marriages grew in the 19^th century as wilderness settlers tried to distinguish themselves from the “savage” Indians, says Martin, author of the book Forbidden Relatives: TheAmerican Myth ofCousin Marriage. “The truth is thatEuropeans were marrying their cousins and NativeAmericans were not.”
And doesn’t God have stern words on the subjectChristie Smith, 37, a Nevada writer, says she felt guilty when she fell in love with her first cousin’s son Mark. “I was trying so hard to convince myself not to have these feelings,” she recalls, “that I went to theBible looking for confirmation that it was wrong.And what I found was the exact opposite: support for cousin marriages.” The patriarch Jacob married two of his first cousins, Rachel and Leah. Smith married Mark in 1999.
The medical ban is lifted; the social stain may take longer to disappear.
