No, you don't have seven literal twins (like the Octomom's children), but the phrase refers to the idea that statistically, there are around seven people in the world who look very similar to you, your "doppelgängers," due to shared DNA and random facial features, though finding an exact look-alike is incredibly rare. The number "seven" comes from studies suggesting each person could have several look-alikes, and while twin births are common (about 1 in 42 children), having seven actual babies at once (septuplets) is extremely rare.
Each year, approximately 1.6 million twin pairs are born around the world, equivalent to one in 42 children globally. Back in the 1980s, this figure was a third lower. While twin births are a chance event, there are two key reasons scientists posit are behind the global 'twin boom'.
Most people are familiar with Identical and Fraternal twins, but in reality, there are 7 different kinds of twins. They are: identical, fraternal, half-identical, mirror image twins, mixed chromosome twins, superfecundation, and superfetation.
According to a 2015 study from the University of Adelaide in Australia, there's about a one in 135 chance that a pair of complete doppelgängers exist somewhere in the world. But the likelihood of someone walking around looking identical to you is only one in 1 trillion.
Semi-identical twins, also known as sesquizygotic twins, are among the rarest types of twinning, occurring when a single egg is fertilized by two sperm.
Fortunately, researchers have already calculated the possibility for us: your chance of spotting a Doppelganger is one in 135, and on average, each person can have around seven doppelgangers. We share the most genetic information with those who are related to us.
Some names for these are:
The first wife (died ante 1770), of Feodor Vassilyev (b. 1707–c. 1782), a peasant from Shuya, Russia, gave birth to 16 sets of twins.
A daisy baby is another name for babies with TTTS. The Twin-to-Twin Transfusion Syndrome Foundation coined the term after its founder planted daisy seeds with her surviving twin son in their backyard. The daisy field is a symbol of hope that all babies affected by TTTS will survive.
Other pregnancy loss-related terms:
Sunset baby: A twin who dies in the womb. Sunrise baby: The surviving twin of a baby who dies in the womb.
Nope. While identical twins often have very similar fingerprint patterns, they're never an exact match. Those miniscule differences, like short or split ridges, are what forensic experts use to tell them apart.
If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes.
Not always. One studyOpens a new window found that 15% of identical twins have some genetic variations due to mutations – that is, changes in DNA. That study found a relatively tiny number of mutations between identical twins (5.2 on average).
One of Africa's largest countries, Nigeria, has been nicknamed “The Land of Twins” by the BBC because it has the highest rate of twin births in the world. In Igbo Ora, in Oyo State in south west Nigeria, the rate is much higher, the last recorded figures revealed an average of 50 sets of twins in every 1,000 births.
High rates of twins are found throughout Central Africa. With 27.9 twins per 1000 births (2.8%), Benin has the highest national average. On the other hand, the twinning rate in Asia and Latin America is very low: often less than 8–10 per 1000 births (0.8–1%).

What causes you to get pregnant with multiples? A multiple pregnancy means you're pregnant with more than one baby. Multiple pregnancy usually happens when more than one egg is fertilized. It also can happen when one egg is fertilized and then splits into 2 or more embryos that grow into 2 or more babies.
The “7 look-alikes” theory is more folklore than fact. While genetics and chance can create uncanny resemblances, true facial twins are rare and usually not an exact match in every feature.
Is it true that there are 7 similar faces in the world? If you have read this article, you would definitely say no. Having said that, it is quite likely that one has a doppelganger in the world that looks somewhat or pretty much exactly like them.
Identical twins occur in about one third of multiple pregnancies. Known as monozygotic twins, a single egg is fertilised then splits into two (or very rarely three or more) creating identical babies with the same genes, physical features and sex.
Sightings and reports of doppelgangers have been around for centuries, and a great deal of superstition has developed around them. Traditionally, they have been viewed as sinister or even evil entities. Seeing a doppelganger has also been considered an omen of misfortune or bad luck.
