AN'S curiosity in the unusual has led him into many fields of adventure. Twins, constituting about one per cent of the births according to Davenport (3) are both so rare and so different that science has for a long time been very curious about their origin, their resemblances and their differences. The dispute as to the relative importance and effects of heredity and environment in moulding hum...

Whether monozygotic (MZ) and dizygotic (DZ) twins differ from each other in a variety of phenotypes is important for genetic twin modeling and for inferences made from twin studies in general. We analyzed whether there were differences in individual, maternal and paternal education between MZ and DZ twins in a large pooled dataset. Information was gathered on individual education for 218,362 ad...

In this study we examine the hypothesis that monozygotic (MZ) twins in historical databases are less discordant for birth weight due to negative selection of severely discordant MZ twins. Furthermore, we test the hypothesis that MZ twins are less discordant for birth weight when comparing a volunteer based twin registry with a population based twin registry, due to selective registration. Data ...

BACKGROUND Studies of twin pairs discordant for autoimmune conditions provide a unique opportunity to explore contributing factors triggered by complex gene-environment interactions. METHODS In this cross-sectional study, thirty-one monozygotic or dizygotic twin pairs discordant for myositis or systemic lupus erythematosus (SLE), along with matched healthy controls were evaluated for antibodi...

Bracelet creases among the twins were examined. A total of 42 pairs of twins (monozygotic twins-16 pairs, dizygotic like sex twins-20 pairs and dizygotic unlike sex twins-6 pairs) from the states of West Bengal and Madhya Pradesh of India were studied for this purpose. High discordance value in dizygotic twins in various types of bracelet creases is found to be sufficient to account for the hig...

This study investigates the formant dynamics of Mandarin and Shanghainese /ua/ in bilingual identical twins. Data collected from two sessions were analysed using Discriminant Analysis. The results show that despite the same organic structure and similar language environment, differences can be found in the formant dynamics of identical twins. However, cross-session analysis suggests that for id...

One of the most interesting congenital malformations to manage is a conjoined twin. Conjoined twins are rare occurrences in obstetric/pediatric practice. More commonly known as Siamese twins, this phenomenon is shrouded in mystery and considered a curiosity by general public. Current technology is lending a helping hand in the early diagnosis of these conditions. Frequently, the twins are born ...

There is a lack of research findings addressing the unique college admissions issues faced by twins and other multiples. The advantages and disadvantage twins face, as reported by college administrators, twins and families are reviewed. Next, recent research addressing twins' birth weight and neuromotor performance, transfusion syndrome markers, the vanishing twin syndrome and monozygotic (MZ) ...

Conjoined twins are twins whose bodies are anatomically joined in utero. The degree to which the twins are attached can range from simple, involving skin and cartilage, to complex, including fusion of the skull(s), brain(s), or other vital organs. There are more than a dozen classifications of conjoined twins [3] but what they all tend to have in common is the sharing of the chorion [4], placen...
