Birth weight in opposite sex twins as compared to same sex dizygotic twins.
The question addressed in the present report is whether the large birth weight differences in dizygotic twin pairs of opposite sex (DZos), especially in 'male first' couples--observed by Blickstein and Weissman (Blickstein I, Weissman A. Birth weight discordancy in male-first and female-first pairs of unlike-sexed twins. Am J Obstet Gynecol 1990;162:661-663) and replicated in the present study-...
متن کاملDizygotic twins with schizencephaly and focal cortical dysplasia.
The case reports of 17-year-old female dizygotic twins are presented. One of the twins had bilateral closed-lip schizencephaly, and the other had focal cortical dysplasia. Septum pellucidum was absent in both cases. The cortical dysplasia in case 2 corresponded to the same hemispheric location with the right schizencephalic cleft in case 1. The combination of schizencephaly and focal cortical d...
متن کاملCraniofacial Fibrous Dysplasia
Fibrous dysplasia (FD) is an osseous growth dis-order, producing immature bone and characte-rized by the replacement of normal bone with fibro-osseous connective tissue. It is a bone dys-plasia that has the potential to cause significant cosmetic and functional disturbances, particularly in the craniofacial skeleton. Cra-niofacial fibrous dysplasia is one of the three types of polyostotic fibro...
متن کاملThe sex ratios of monozygotic and dizygotic twins.
Fellman and Eriksson (2010) cited my suggestion that the sex ratio (proportion male) of monozygotic (MZ) twins is lower than that of dizygotic (DZ) twins (James 1975). Here I offer elaborations on and potential explanations for this.
متن کاملNo effects of prenatal hormone transfer on digit ratio in a large sample of same- and opposite-sex dizygotic twins
Hormone-transfer theory proposes that the hormonal milieu of one twin may influence the other. In opposite-sex twins it has been proposed that hormonal transfer may produce a masculinizing effect in females. The second-to-fourth-finger ratio (2D:4D) has been proposed as an index of the level of prenatal androgens and could, theoretically, be used to detect hormone transfer. Previous examination...
