One , Why are twins called twins
1. If they are identical twins, one fertilized egg splits into two, and then continues to develop into two fetuses. Growth, because the two fetuses are split from one fertilized egg, the chromosomes of the two fetuses are exactly the same and the sex is the same, so it is impossible to have identical twins.
2. Only when a woman releases two eggs at the same time, and the two eggs are combined with different sperms, can twins be born after fertilization.
3. Therefore, as long as the genders of identical fetuses are the same, the genders of fraternal fetuses can be the same or different. As long as they are twins, they must be produced by fraternal fertilization, so the idea of identical twins is unscientific

Twin pregnancy can be judged by ultrasound. If the two fetuses have different genders, they must be dizygotic twins. A twin pregnancy formed when two eggs are fertilized separately is called a dizygotic twin pregnancy and is related to the use of ovulation induction drugs, assisted reproductive technology and genetic factors. Two fetuses have their own genetic genes, resulting in fetal blood types and genders that can be the same or different.
