International group of scientists from America, Sweden and Netherlands has made an unusual opening - monoovular twins are not absolutely identical, they have distinctions at a genetic level.

“In spite of the fact, that as a whole genomes of monoovular twins are very close, there are small distinctions in almost all the cases”, - inform heads of the research Yang Dumansky and Karl Bruder.

Earlier scientists believed, that if one of monoovular twins fell serious ill, and the other remained healthy, it happened under the influence of an environment. Now experts have found out, that it not so.

Researchers have found out, that one of two twins may have certain fragment of DNA, while the other doesn’t have it.

Though experts mark also that fact, that somatic cells are really subject to influence of an environment, therefore it is impossible to assert confidently that distinctions are congenital.
