Twin Mythconceptions: False Beliefs, Fables, and Facts about Twins sheds new light on over 70 commonly held ideas and beliefs about the origins and development of identical and fraternal twins. Using the latest scientific findings from psychology, psychiatry, biology, and education, the book separates fact from fiction. Each idea about twins is described, followed by both a short answer about the truth, and then a longer, more detailed explanation. Coverage includes embryology of twins, twin types, intellectual growth, personality traits, sexual orientation of twins, marital relationships, epigenetic analyses, and more. Five appendices cover selected topics in greater depth, such as the frequency of different twin types and the varieties of polar body twin pairs. This book will inform and entertain behavioral and life science researchers, health professionals, twins, parents of twins, and anyone interested in the fascinating topic of twins.
