Abstract
Cholesterol levels were measured in the cord blood of 30 pairs of monochorionic and 22 pairs of dichorionic monozygotic (MZ) twins. Cholesterol levels were significantly higher in female twins when data was combined over chorion type. The type of chorionic development had no significant effect on variation among twin pairs. Chorion type did have a significant effect on the within-pair variation. The variation within dichorionic pairs was more than 5 times that within monochorionic pairs (P < .01). The variation in placentation may have a significant effect on within-pair variation in serum cholesterol of newborn MZ twins.
