If one egg cell unites with one sperm cell at fertilization nine months later twin brothers are born, the brothers received their identical DNA from the mother.

One egg cell unites with one sperm cell at fertilization nine months later twin brothers are born.

There are two types of twins. In one example, dizygotic twins. It can occur when two of her eggs are present in the mother's body at the same time and both are fertilized. Each will grow into their own baby. Any baby that grows out of it will not have the same her DNA. This is because each egg and sperm does not have the same DNA. They are basically like other siblings, but were born at the same time.On the other hand, another type of twins is called identical twins. There is only one egg and only one sperm can fertilize it. A fertilized egg usually divides into a baby. However, once fertilized and division begins, the eggs can fall apart. After falling apart, each half begins to split and grow into a baby. And since these two babies came from the same fertilized egg, they have the same DNA. Dizygotic twins each have their own DNA, but identical twins share the same DNA.

Even if identical twins have exactly the same DNA, they are not exactly identical. So mothers can tell identical twin babies apart. However, identical ones have the same genotype. In any case, they are born from the same fertilized egg. Furthermore, DNA is basically like a guide for building something, so even though identical twins aren't exactly identical, the way their bodies are built is random. is able to have an identifiable fingerprint. Another important factor in why identical twins are not exactly identical is the environment in which they were raised. In other words, in basic biology, it is said that identical twins have the same DNA.
