Twins and twins: what is the difference and is it so great

In recent years, the number of cases when a mother is born several children is significantly increased. Most often this is twins, but there are often variations of triplets, and quadruples appear periodically. Scientists are lost in conjecture, what exactly provoked a kind of ejection of multiple pregnancies. Basically sin on the ecological situation (yet in more "pure" times even twins were a rarity). There are also exotic assumptions, for example, information congestion of the surrounding world, which somehow stimulates the appearance of several children at the same time.

Most people are deeply indifferent to the factors that determine the multiple pregnancy. Moreover, many future parents even attract the opportunity to get two offspring at once. Like, once tortured - and free. Yes, and the children together are more fun, they will not be bored and without friends will not remain - the friend in fact was born simultaneously and always near by. And with such reflections more and more curious: there are twins and twins - what's the difference between them?

Question of terminology

In medicine, to be honest, there are no such terms. These definitions are formulated by the people in order to determine which of the pairs born at the same time as a mother, originated from different eggs, and which one from one. The difference between twins from twins is exactly this: for the first two, the second, took place from the general.

What is closer to nature

More natural when multiplicity is considered to be the fertilization of several eggs. Yet mammals usually give birth to several babies at the same time, which is normal. Perhaps, among the offspring there are twins and twins. What is the difference? In the number of oocytes. When one is divided (already fertilized), this is not very normal. Not without reason in this process the risk of occurrence of Siamese twins is great. Notice, twins, not twins!

Curious moments

Some scientifically established facts are interesting, with twins and twins noted. What is the difference between their psychological, physiological and mental arrangement? The first - quite separate individuals and from each other depend no more than sister brothers of different ages. The second often feel each other, choose the same profession and similar sexual partners, sometimes even suffer from the same diseases at the same time. Even in the direction of mental development, there are differences. One is a mathematician, the other is a humanist. It's twins. And twins (which is the difference) - most often both "physics" or "lyrics". Even the sex of the twins is always the same. The external similarity of identical children is also striking, while the raznoyaytsev can resemble one to mother, the other - to the pope.

How to make twins

There are no clear recommendations that guarantee the appearance of twins. But nobody canceled genetics. If in a kind at mum (on a female line!) There were twins, the chance to give birth to her same raises also at the daughter. There are folk ways of increasing the likelihood of conceiving a couple of kids instead of one. So, it is considered that if before conception for two or three months to start drinking folic acid, the chances will increase. And if you add to this the increased use of eggs, nuts, milk and whole grains - you do not have time to look back, as twins and twins are born . Scientifically not proven, but many believe. But the checked up observation: a multiplicity more likely after 30 years, and at already giving birth to the woman with some excess of weight. They say that twins are more likely if they start with a nursing mother.
