title: Zygosity assessment by self-report; research reports; human interest.
abstract: The research implications and personal perspectives associated with twins' and families' self-reports of zygosity are reviewed. This is followed by summaries of recent research reports including a possible first case of the freemartin effect in humans, twin-singleton comparisons of mental health in Japanese students and mechanisms associated with ART-induced monozygotic twinning. A look at twin stories in the media includes the extraordinary revival of an infant male twin, the career decision of a pair of MZ twin basketball players and the loss of a five-year-old triplet.
