The blood types, together with erythrocyte and plasma protein types were determined in 10 pairs of twins born after embryo transfer to the contralateral uterine horns of previously inseminated recipients. These estimations were carried out at the age of nine weeks. According to the haemolytic test, most of these pairs of twins had identical blood types, ie, no erythrocyte mosaic could be demonstrated and the blood type corresponded to that of the recipient's calf. In the cases where mosaicism could be demonstrated, the recipient calf's blood type predominated. The reason for this bias remains unclear although the suggestion that the recipient's calf had developed further and was thus able to influence the haematopoietic tissues of its co-twin is worth considering.
在将胚胎移植到先前已授精受体的对侧子宫角后出生的10对双胞胎中，测定了血型、红细胞类型和血浆蛋白类型。这些测定是在9周龄时进行的。根据溶血试验，这些双胞胎中的大多数血型相同，即未发现红细胞嵌合体，血型与受体小牛的血型一致。在可证明存在嵌合体的情况下，受体小牛的血型占主导。尽管受体小牛发育得更好，因此能够影响其孪生小牛的造血组织这一观点值得考虑，但这种偏差的原因仍不清楚。
