The world of twins is full of particularities and curiosities that we like to get to know. We’ve gathered some for you.

You twins always arouse great curiosity among everyone. Regardless of whether or not there is a physical similarity, the fact that they share nine months of intrauterine life becomes a distinct aspect that can effectively influence their growth and life course.
Therefore, parents also need to have a different orientation, in the sense of learning the best way to deal with their children, accepting their similarities but, above all, respecting their individuality.
Gemini: true or false?
Surely you have heard the expression: “real” or “false” twins. These are more popular terms that refer to the way in which the fertilization process took place.
The “true” ones are, more precisely, univitelline or monozygotic, as they originate from the same ovum that, after being fertilized by a spermatozoon, split into two, creating two distinct embryos.
The “false”, or bivitelline or dizygotic, originate from different eggs, each of which is fertilized by a different spermatozoon.
Through these designations and explanations, it becomes easy to understand that monozygotes share the same genetic information, hence their physical similarity. In any case, it should be noted that dizygotics can also have an identical appearance.
How to raise twin brothers?
Twins must be educated, respecting their individuality, personality and differences, so that their autonomy is stimulated.
It is common for one twin to dominate and/or depend on the other, as well as excessive protection, especially if one is more fragile in terms of health, for example.
In order to encourage individuality, you should avoid dressing them the same; give them the same toys; and compare them constantly. For this reason, there are specialists who recommend that, even at the same age, they should attend different classes, in order to avoid comparisons and make one of them a model to follow for the other.
It is in the relationship with other children of the same age (but not their sisters) that each twin builds his personality and gains self-confidence. Accepting that twins have differences is key to avoiding emotional and developmental problems.
Gemini: peculiarities and curiosities
They don’t have the same fingerprints
Fingerprints are not just the result of DNA, so they will be different in twins, forming between 6 and 13 weeks of gestation.
Have inverse asymmetric traits
Approximately 25% of identical twins develop with their faces next to each other, which is why they act as authentic mirrors or reflections of one another.
Even identical twins do not have the same genetic make-up
Yes, identical twins are generated in the same egg and have the same genome. However, their genetic makeup is not necessarily the same.
Tall women are more likely to have twins
The explanation lies in IGF, a protein released by the liver which, when present in greater quantity, stimulates the ovaries more and ovulation. Thus, the more IGF a woman has, the more chances she has of conceiving twins.
Women who consume a lot of dairy are more likely to have twins
Cow’s milk also has IGF, the protein that stimulates ovulation. Thus, women who consume dairy products are up to 5 times more likely to have twins than women who do not eat dairy products at all.
Having different parents… It’s possible
Yes, this is a rare situation that only happens once in a million. For this, it is necessary for the woman to release two eggs in a month and have sexual intercourse with two different partners, with a maximum distance of 5 days between intercourse. Thus, each egg can be fertilized by sperm from different men.
Interact in utero
From the 14th week of gestation, the twins already interact with each other, touching each other’s bodies.
About 40% of twins invent their own dialects
Many twins create what are called autonomous languages, which act as models in language development. At its base, there may be inverted words and onomatopoeic expressions. This is a very common form of communication and play between twins, especially during childhood, although it is not exclusive to them.
