Most often, twins are born in Africa and Asian countries – less often. In Russia, the birth of twins barely exceeds 1%. Depending on what depends on the possibility of distinguishing identical twins, we will discuss this in this article.
Diet + genes = twins:
Scientists believe that there are genes that lead to the birth of twins. As discovered by British geneticists, many pregnancies may be associated with IGF1 genes, and more specifically with the insulin-like growth factor protein, co-regulating growth, development, and differentiation. between cells and body tissues.
The researchers analyzed data on the weight of nearly two thousand newborns – not twins. It turned out that those who gave birth to their twin mothers weighed more. If a child was born after twins, the average weight was 226 grams compared to other children. Who were born before the twin – 134 grams. All mothers who have twins have high levels of IGF1.
This protein participates in the growth of the fetus and thus affects the weight of the newborn. In addition, IGF-1 stimulates egg production in women, thus contributing to multiple pregnancies.
A woman born in a twin family is more likely to have twins if she follows a specific diet properly. According to the work of the American doctor Herri Steinman, the possibility of the birth of women who have completely abandoned twin dairy products five times less than those who eat everything and plants that take milk.
The problem still lies in a growth factor similar to that of insulin 1. In vegetarians, its level is much lower, confirms these statistics – countries that usually consume a lot of dairy products – where the birth of twins is generally larger.
No way out:
The identical twins have the same group of genes and it is almost impossible to distinguish between their biological samples (blood, saliva, hair) using a normal DNA analysis. This poses problems when investigating crimes.
American crime scientists solve this problem by developing a method based on the replication of genetic DNA. Throughout life, small chemical markers appear on the DNA (called transgenic factors). These are not mutations, they do not alter the structure of the genome, but affect the activity of certain genes in the cells and tissues of the body. These signs – result in new habits, fatigue, anxiety and a change in lifestyle.
