post-title

Unless you're a twin brother or you have a couple of them around, you probably know general things about them, like they look alike, that their parents dress them the same, even that they have a special connection, but that's it.

Some people have wanted to have a twin on many occasions because they think they could cover each other to share responsibilities such as classes at school or work shifts.

The reality is that there is much more to twins than just what is seen physically.

1. Twins can have different biological parents

Each month, a woman releases an egg that can be fertilized by a sperm. However, there are times when two ovules are released, which could be fertilized by separate donors.



2. They can be of different races

If the twins' father and mother are of mixed races, their eggs and sperm contain a different genetic potential. There are millions of possible outcomes for both babies, and in very rare cases, the two could be of a single race.

3. The separated twins have come to live very similar lives

There are several stories that are known about twins who were separated at birth and lived lives that strangely reflect the other's. Sometimes, their similarities go beyond a coincidence, such as marrying a woman with the same name or calling their children with the same name; have the same professions; to get sick at the same time.



4. Your children will be genetically brothers

If twin men have children with identical twins, their children will legally be classified as cousins ​​among them, but genetically they will be siblings because they will have the same genetic makeup.

5. Moms who have twins are healthier

It is believed that women who give birth to twins are healthier and that these twins are an evolutionary adaptation to transmit the genes of these mothers twice in a pregnancy.

6. Higher women are more likely to have twins

Countries with an average proportion of higher women have higher twin birth rates. The taller people have higher levels of growth hormones, and in women this makes their ovaries more susceptible to having twins spontaneously.



7. Women who consume more dairy products also have more possibilities

Women who consume products of animal origin, especially dairy products, are five times more likely to have twins.

8. The twins show signs of their bond from the uterus

According to an Italian study, the twins begin to touch in week 18 of their development. They also gesticulate among themselves in the womb.

9. They have reflections as if they were in front of a mirror

Some twins are set opposite each other in the belly and become a reflection of the other: one of them will be right-handed and the other left-handed, and the birthmarks will appear on opposite sides of the body

10. You may listen to the other's thoughts

Some twins who are joined by the head share a thalamus. The thalamus is a part of the brain that controls physical sensations and motor functions. As a result, these twins can see through each other's eyes, hear their thoughts and feel the same sensations.

11. The mother's body can adapt to them

If a mother is breastfeeding her twins, her breasts can individually adjust their temperature for the comfort of each twin!

12. The navel is the only way to say that they have been separated

The navel, scar left by the elimination of the umbilical cord, is the reminder that each one is slightly unique.

13. If a woman is a twin, she will be more likely to give birth to twins

They are more likely if she is or if she has siblings who are twins.

14. Twins do not have identical fingerprints

Although they have identical DNA, fingerprints are formed because they touch the amniotic sac, whose shapes and ridges create individual fingerprints.

15. Twins are twice as likely to be left-handed

16. Twins can be born months apart

Due to complications, such as the mother breaking source prematurely, sometimes the twins may be born weeks or months apart. The record time between births is 87 days: almost 3 months.

17. The twins could become the perfect criminals

Because they can share up to 99.9% of the same DNA, forensic experts would have difficulty fixing the crime on a specific twin if each of them had different alibis and denied a crime. This means that they could be free.
