A case of opposite-sex co-twins who married one another was recently reported. This case raises questions concerning the bases of mate attraction and adopted children's right to know their biological origins. This overview is followed by summaries of recent studies of familial twinning, food neophobia and monozygotic twins discordant for phenotypic sex. Several topics of general interest are also presented.
