In recent years, multiple births have tripled worldwide, this is because women increasingly expect more to be able to have children, and to a greater extent new methods of assisted fertilization.
So there are many doubts that assail us about the twins and twins who really are amazing. Here you have 10 curiosities that few people know about twins and twins.
Ten curiosities about twins and twins you do not know
1- Twins are different and twins are the same:
Twins are two independent siblings that are conceived at the same time, while twins come from the same sperm and therefore they share genetic code, which makes them almost physically identical children.
2- Twins may have different parents:
Women may have several ovules at a time, so there is a possibility that if that woman has sex with different men in a short period of time, she may become pregnant. two different sperm, giving rise to two twins from different parents.
3- Thechildrentwins can be of different races:
If the father and the mother are of different races, there may be a curious genetic combination in which one of the children predominates the race of the mother and in the other the father's Los 4- The
childrentwins do not have identical fingerprints:Although they share 99% of their genetic information, the fingerprints are not the same. This is because the tracks are created between the 6th and 13th week of pregnancy, when the babies touch the amniotic sac and lines and grooves are formed in each baby's hand completely different. Los 5- The
identical twins may have opposite symmetrical features:A study has revealed that 25% of the twins grow inside the womb facing each other, which one ends up being an exact reflection of their twin: one right-handed and the other left-handed, equal spots on opposite sites, etc.6- Mothers of
twins could live longer:A nineteenth-century study revealed that mothers of twins were healthier and stronger, so they were more likely to live longer than the rest. This was interpreted as a genetic evolution in which strong mothers could transmit their genetic information twice as a means of survival of the species. Of course, that study is currently unfounded due to assisted reproduction.7- Highest mothers who drink milk are the most likely to have
twins:Tall women have higher levels of IGF, a protein that stimulates growth and increases ovulation in women. The same goes for women who consume dairy products, since cows also produce IGF that is transmitted through milk.8- The
twins and twins may not be born on the same day:It is rare but some premature births there may be a difference of between 1 week and two months between the birth of one and the other.9- The best way to differentiate the
twins is through their navel:Being a scar every one of them will have it in a different way.10- The
twins are twice as likely to be left-handed as the rest:Twenty-two percent of the twins tend to be left-handed, compared to 10% of the rest of the population.
