Why Twins Are Born?

People are very fascinated with twins and other multiples. Birth of twins depends if they are identical or fraternal. First way (fraternal) is when multiple eggs are released or there is more than one ovulation. Both eggs are fertilized and you have fraternal twins. Second (splitting), one egg is release but splits in two. Identical twins are made. Identical is always the same sex. Fraternal can be two girls, two boys or a boy and a girl born at the same time.
