Sirenomelia dipus in a dizygotic twin
The Indian Journal of Pediatrics, 2002A rare case of sirenomelia in a LBW, IUGR & second of a dizygotic twin having multiple congenital anomalies is being reported. Apart from the features of sirenomelia, the newborn had a single umbilical artery, radial hypoplasia, total anorectal & urogenital agenesis and undetermined sex.

Coital rates and dizygotic twinning
Journal of Biosocial Science, 1972There is some evidence, mostly of an epidemiological nature, that coital rates may be positively associated with dizygotic twinning. It is suggested that this link is causal, in which case an explanation becomes available for some curious—and hitherto unexplained—features of dizygotic twinning rates by maternal age and legitimacy.

Congenital biliary dilatation in dizygotic twins [PDF]
Pediatric Surgery International, 2004 Congenital biliary dilatation (CBD) of different types was recently noted in dizygotic twins. Our cases suggest the possibility of hereditary involvement in CBD. On the other hand, CBD discordance in six sets of monozygotic twins has been reported, which would suggest that the occurrence of CBD is not compatible with single gene control, although ...

Fetal alcohol syndrome in dizygotic twins
The Journal of Pediatrics, 1975A pair of fraternal twins with stigmata of the fetal alcohol syndrome are described. Apparently differences in susceptibility to the dysmorphogenic influence of ethanol caused one twin to be more severely affected than the other one. Both infants are growing poorly postnatally, and both are at risk for retarded development.

Gestation and birthweight in dizygotic twins [PDF]
The Lancet, 2002 Sir—Ruth Loos and colleagues (Aug 18, p 560) report that, within dizogotic twin pairs, same sex female twins have longer gestations than same sex male twins. They further note that in mixed sex twins, gestation is longer than for same sex male twins, and that the male co-twins are larger than those in same-sex pairs.

Handedness in opposite and same-sex dizygotic twins: testing the testosterone hypothesis.
NeuroReport, 1999Prenatal exposure to testosterone is proposed to promote development of the right hemisphere and increase the incidence of sinistrality. This proposition was tested by comparing the hand preference of 59 opposite-sex and 61 same-sex dizygotic twins ...

Lifestyle factors in monozygotic and dizygotic twins
Genetic Epidemiology, 1988AbstractIn examining genetic influences on biological variables using twins, it may be important to examine the distribution between and within twin pairs of demographic and lifestyle factors that may themselves affect the biological variable being studied.

Sirenomelia and anencephaly in one of dizygotic twins
Teratology, 1986AbstractThe combination of sirenomelia and anencephaly was observed in a stillborn dizygotic twin. A review of the literature revealed no other patients reported to have both conditions. Various explanations concerning the genesis of sirenomelia, and also the combination with anencephaly, are discussed.
