The Heritability of Twinning in Seven Large Historic Pedigrees. |
|
ABSTRACT |
|
|
|
It is widely recognized that dizygotic twinning (DZT) runs in families, but estimates of heritability from twin and family data are remarkably scarce and vary considerably. Here, we traced seven large, sometimes historical, multigeneration pedigrees from West Africans, fin de siècle French Jews, Canadians (two pedigrees), and the French royal family, in which twin births were recorded. We estimated heritability of twinning (of all types) as zygosity information was not available, diluting the true DZT heritability by a third or so. The estimates in the range 8-20% are remarkably consistent across time (8-19 generations) and ethnicities and also consistent with twin and family estimates. |
