What causes an egg to split into twins?

This type of twin formation begins when one sperm fertilizes one egg (oocyte). 1 As the fertilized egg (called a zygote) travels to the uterus, the cells divide and grow into a blastocyst. … Simply put, monozygotic twins happen when a single fertilized egg divides into two. From there, two embryos grow into two babies.

Can you have twins if it doesn’t run in the family?

Remember, monozygotic (identical) twins don’t run in families—they are random.

That being said, twins that share a close physical resemblance are more likely to be identical than fraternal.

Which parent is responsible for twins?

The gene versions that increase the chance of hyperovulation can be passed down from parent to child. This is why fraternal twins run in families. However, only women ovulate. So, the mother’s genes control this and the fathers don’t.

What’s the likeliness of having twins?
