SUMMARY Birth weight has been analysed in a series of 528 unselected, newborn twins pairs of known zygosity, in relation to sex, placentation, duration of gestation, maternal age and parity. Monozygotic twins weigh less than dizygotic twins, even when the named variables are allowed for. Possible reasons for this are discussed.
