Twins are like two friends who decide to go on a special adventure together, but how they start that journey depends on if they're identical or fraternal.
When identical twins are born, it’s like one person made two copies of themselves. Imagine you have a favorite cookie recipe, and you make two batches at the same time, both cookies taste exactly the same. That's what happens in your body: one egg meets one sperm, and instead of becoming just one baby, it splits into two, like magic cookie dough splitting into two identical batches.
Now, fraternal twins are more like siblings who happen to be born at the same time. It’s like when you and your brother or sister both decide to go on that adventure together, but you’re not exactly the same. Your mom’s body makes two eggs, and each one meets a different sperm. So they start off as two separate babies from the beginning.
Sometimes, identical twins are called monozygotic, and fraternal twins are called dizygotic, it's just another way to describe their special journey!
