The Twin Quiz


Twins QuizTwins are defined when two babies are born to a mother at one birth. There are two types of twins, monozygotic and dizygotic. How often are twins born? What different kind of twins are there? What are monozygotic twins? What are dizygotic twins? How many twins share the same placenta? Do all identical twins have one placenta?

When a woman becomes pregnant, the process of conception does not always stop at one baby. A pregnancy of more than one fetus concurrently is called a multiple pregnancy. While the majority of multiple pregnancies refer to twin/triplets, with the increase in the use of fertility drugs, multiples have been growing in number in recent years. Twins can happen with one fertilized egg splitting or two eggs being fertilized by separate sperms.

Dizygotic twins/trizygotic triplets (fraternal or non-identical) are created when a female releases more than one egg or ovulates two or three times and all eggs are fertilized. Monozygotic (maternal/identical) twins or triplets are created if one egg is released, only one sperm fertilizes the egg, and the egg splits into multiple embryos.
