Abstract
There is evidence, both direct and indirect, that there is a continuum in sex ratios across the various sorts of twin zygote. The evidence for low sex ratios is strong in respect of the rarer sorts of twins (monoamniotic and conjoined), but the contrast between dichorionic monozygotic and monochorionic monozygotic pairs is suggestive too.This publication has 15 references indexed in Scilit:
