pubmed-article:2753741 | pubmed:abstractText | The influence of twinning on developmental stability was measured by comparing fluctuating asymmetry in dermatologlyphic traits in monozygotic twins, dizygotic twins, and singletons. Despite reports that twinning has been reported to influence development of traits such as birth weight and I.Q., no significant difference in fluctuating asymmetry was found between different zygotic categories. | lld:pubmed |
