The world is full of similar people who are not connected by blood ties. How is it possible that two people born and raised in different parts of the world look like two drops of water? Is there a clear scientific explanation for this phenomenon?

People who are similar to each other and are not relatives - is this possible? It turns out yes. A French photographer once had a wonderful idea. He found and captured on film similar people who were not connected by any blood ties. His name is Francois Brunelle. It took him about twelve years to realize his idea. The photographer tracked people with terribly similar features around the world and helped them find their doppelgangers. Some photos of similar people from the work of Francois Brunelle are presented in this article. Carefully study the proposed images and compare how many similarities have completely strangers who have no blood relationship.

Every person in this world has 7 twins

It is said that every person in this world has at least seven very similar people. One can easily agree that this assumption is rather frightening and unnatural. It is hardly possible to find two exact copies on our planet, identical as two drops of water. Even blood twins have features that, at least a little, but make it possible for others to distinguish them, not to mention a stranger who lives on the other side of the Earth.

Not the same, but, nevertheless, incredibly similar people still occur, and not as rare as it might seem. They live in different cities, countries, continents, lead a completely different way of life. They do not have common genes, they differ in language and culture, but their similarity really cannot be denied.

Same looks, same personality?

We all know that there are similar people. Is this purely a superficial resemblance? Can a person and his counterpart from another country have the same character traits and activities? It would be strange and surprising at the same time. In fact, it happens in different ways. For example, there once lived in Rome one emperor named Maximinus (beginning of the 4th century AD), and so, looking at his bust, you can see in his features the familiar dictator from the 20th century, Adolf Hitler. These similar people not only had the same facial features, but both were dictators in their time, and both perished ingloriously.

It is quite difficult to answer this question, modern science does not have exact answers, there are only guesses. One of the most likely versions is the one that explains the external similarity of complete strangers with an identical genetic device. For a reason that has not been clarified to date, similar people have the same DNA to the smallest detail.

These twins are also called biogenic. This means that they have the same genetic material, but their biological parents are different. It happens that people can be similar and live in different places at the same time and be the same age. Some can be separated by years, centuries and even whole millennia. Natural diversity, it turns out, is not unlimited, there are billions of people in the world, and there is always a chance of a random coincidence of genetic sets.

secret relationship

Scientists consider it quite possible that similar people are very, very distant relatives. Having resorted to elementary mathematical analysis, we can make the following calculations: the average citizen after eight generations will be a descendant of 256 relatives who, one way or another, are related by blood ties. If we imagine that 40, 50 or more generations have passed, relatives will be in the millions. And no one knows where the genetic material will match, on which generation.

In card jargon, genes are shuffled like cards in a deck, but at a certain point, the same “hands” fall out with a minimum probability. Then twins are born into the world, people similar to each other, like two drops of water. Perhaps nature has its own plans in this regard, its secret goals.

Search for doubles in the network

Today, there are many sites on the World Wide Web with which you can find an exact copy of yourself among the stars of show business, great emperors and historically significant leaders from a photograph. They are also looking for their doubles among the most ordinary people of their different cities and states. you just need to upload your photo in a certain format, and after a while, search engines will be able to pick up a couple of twins for you, or at least people who will be very similar to you.

Such sites are quite popular, because it is actually interesting to know, and even more so to see your double. It's like meeting yourself in a parallel world. Before the advent of the Internet, this was almost impossible to do, but now there are many opportunities for active search, and why not take advantage of them?

Miracles, and only

Twins are a phenomenon that is interesting in itself. People are more or less accustomed to the similarity of blood twins and granddaughters and their great-grandmothers, but to meet a person who is exactly like another person who is not a relative of him, and even lives thousands of kilometers away, this is already more interesting.

Who knows, maybe in the future scientists will figure out how to use this quirk of nature. It is likely that the similarity of genomes can open up incredible prospects in such a field of medicine as transplantology. As biologists assure, the chance of an exact match of genetic sets tends to zero indefinitely. However, partial copying of genes is quite normal, which proves that all of humanity is one big family.

Chromosomes that are identical in appearance in the cells of dioecious organisms are called autosomes. A pair of distinct chromosomes that are not the same in males and females are called sex chromosomes. The total number, size and shape of chromosomeskaryotype

Such differences in sex chromosomes are characteristic of most animals, including humans, but in birds (including chickens) and butterflies, the opposite pattern is observed: females have XY chromosomes, and males have XX. In some insects, such as orthopterans, there is no Y chromosome at all, so the male has the X 0 genotype. The figure shows the human sex chromosomes.

If two X chromosomes get into the zygote, then the girl is XY XX The boy will turn out if the X chromosome comes from the mother, and the Y chromosome comes from the father

2. Inheritance of sex-linked traits. Molecular (gene) and chromosomal diseases Genes located on the sex chromosomes are called sex-linked. There is a region on the X chromosome for which there is no homologue on the Y chromosome. Therefore, in males, the traits determined by the genes of this site appear even if they are recessive. This particular form of linkage explains the inheritance of sex-linked traits such as color blindness, early baldness, and hemophilia in humans.

Hemophilia is a sex-linked recessive trait in which the formation of factor VIII, which accelerates blood clotting, is disrupted. One of the best documented examples of the inheritance of hemophilia is found in the bloodline of the descendants of Queen Victoria of England. It is believed that the hemophilia gene arose as a result of a mutation in Queen Victoria herself or in one of her parents.

Hemophilia gene inheritance variants: Genotype Phenotype XH XH Healthy female XH Xh Healthy female (carrier) XH Y Healthy male X h. Y The male is hemophilic X h The hemophilia gene in the homozygous state is lethal.

P female carrier X healthy male F Healthy girl Girl carrier of the hemophilia gene Healthy girl Hemophilia boy

Modern possibilities of medical genetic counseling make it possible to determine the risk of hereditary diseases during pregnancy planning, including: cystic fibrosis phenylketonuria hemophilia A Duchenne myodystrophy neurosensory non-syndromic hearing loss, etc.
