Twin Pregnancy: Often the question is how twins are born. Which women have more chances of having twins? What is the science behind twins? The phenomenon of giving birth to more than one child is called multiple pregnancy in medical terms. This means that a woman has two or more children in her womb. These can be from the same egg or different eggs. Oxford's new research states that 1.6 million twins are being born every year in the world. According to the Cleveland Clinic, one in every 250 pregnant women is likely to have twins. In such a situation, let us know the complete science of the birth of twins...

How twins are born

When twins or more children are born from a single egg, they are called identical. This happens when one egg is fertilized by one sperm. After this, the fertilized egg splits into two or more parts, which is rare. Even the faces and nature of these children match. On the other hand, children born from different eggs are called fraternal. This happens when two or more eggs are fertilized by different sperm. In simple words, when two different eggs are fertilized in the womb or when one fertilized egg splits into two embryos, twins are born.
