Abstract The Badgett quadruplets are diagnosed by us as a set of two-egg, trichorionic quadruplets. The set, consists of four little girls, three of whom (Jeraldine, Joyce and Jeanette) are inseparable on any grounds known to us and are therefore adjudged to be one-egg triplets. Physically, as is shown in the photographs, they are as similar as almost any pairs of one-egg twins. They are also inseparable on the basis of palm and finger-prints, which though rather inadequate, are at least consistent with the above diagnosis. Finally, the triplet girls are essentially equal in mental ability. In all these respects they differ much more from Joan, the fourth member of the set, than they do among themselves. Joan, then, is diagnosed as a “sibling” of the one-egg triplets. This diagnosis is not inconsistent with, or at least not irreconcilable with that of Dr. Sinclair, who thought that because the set was trichorionic it must be trizygotic. There is strong evidence of a genetic basis for multiple births in the present case, which a perusal of the accompanying pedigree will make clear. A theory to account for the frequent occurrence of both one-egg and two-egg twins in the same pedigree is presented and discussed. This content is only available as a PDF. © Oxford University Press
