There are several types of twin babies

Twin babies have many different

The world of twins is full of mysteries. We can see twins who look very similar and have similar heights, as well as twins who look alike and have very different heights. There is also a kind of twins that are easily overlooked by us, and that is twins.

Identical twins

In fact, identical twins are twins in the true sense. The "wordless book" they have comes from the same egg cell and sperm. 24 hours after the egg cell was fertilized, after it split into two cells for the first time, these two cells, which should have been closely connected, accidentally separated. From now on, we will have the same password and grow and develop separately. They looked like photocopies, with the same gender, similar looks, blood type and physical fitness. Of course, there will be some subtle differences. Since they grow and develop in the same uterus, one of them digests and absorbs more nutrients while the other digests and absorbs less.

Fraternal twins

If two eggs are released at the same time during the ovulation period, these two eggs will fuse with two male sperm in the bilateral fallopian tubes to produce two sperm-egg combinations.

The twins formed by the combination of these two sperm and eggs are fraternal twins. Their appearance, blood type, height and gender may be different. So if the wife is pregnant with twins, they must be fraternal twins. Such twin babies are more like brothers and sisters in a big family.

PS: Of course, identical twins and fraternal twins are rare, and this is closely related to the family genes brought by the wife! So when you confirm that your wife is pregnant with twins, you can laugh smugly, but don't forget to put in a lot of effort and love for 1+1=4!
