Is it true that identical twins are genetically identical?
It's a basic premise of human biology that's taught in elementary schools all across the world: Identical twins are genetically identical since they are born from the same fertilised egg. It's true that identical twins have the same DNA code as one another. This is due to the fact that identical twins are made out of the same sperm and egg from their father and mother. (Fraternal twins, on the other hand, are made up of two different sperm and two different eggs.) Normally, the egg and sperm combine to form an embryo, which then develops into a human infant. Identical twins, on the other hand, divide into two embryos early in development. Instead of one baby, two are produced. According to new research, even if identical twins have highly similar genes, they are not identical. The research sheds new light on why two people who share the same embryo can have such disparities in phenotype, as biologists refer to a person's physical appearance. While the two newborns h...
