Why are some twins identical and some fraternal?

Identical Twins are developed, or formed, when one of Mom’s fertilized eggs splits into two, and each of the halves develop into a separate baby. The split happens within the first 12 days after the egg has been fertilized. If one of the halves splits again, you have identical triplets. If both halves split, you have identical quadruplets.

Fraternal Twins are two separate eggs that are fertilized and then grow into two babies. Fraternal Twins are the most common type of twinning, and the most common type of triplet, quad, quint – and so forth.

Do Identical Twins have the same Emotions?

The fact that identical twins are two different people surprises a lot of people. There is a general assumption that because identical twins share the same DNA, they are carbon copies of each other. Trust me, there is no such thing as identical. Identical twins share the same DNA – it’s not identical DNA, by the way - but once the egg splits, each twin develops on their own. Identical twins develop their own personalities, character, likes and dislikes, hobbies, and emotions just as any other siblings do. They may share some very similar traits, but each twin is their own individual person. It’s fun to watch our own boys as they grow and develop. One likes broccoli, the other prefers green beans. And if you give them cheese and crackers – one will eat the cheese, the other the crackers.

Do identical twins have identical fingerprints?

No. While identical twins share the same DNA, no two sets of fingerprints are exactly alike – including twins. In fact, some mirror twins (identical twins with mirrored characteristics) have fingerprints where the swirls run in opposite directions from their twins’ fingerprint

At what weeks are identical twins usually born?

Multiple pregnancies have a shorter gestation period than singleton pregnancies. The reasons vary (twin pregnancies are high risk pregnancies and are susceptible to more complications than singletons, often leading to early or premature births). The average gestation period for twins is 36 weeks, but it is not uncommon for twins to be born as early as 28 weeks, or as late as 40 weeks. Twins are considered full-term at 38 weeks, and are generally considered ‘early’ if born prior to 35 weeks. Most doctors won’t let a twin pregnancy go beyond 38 weeks because of complications that may occur. Like other babies, twins born prior to 35 weeks may spend time in the NICU to finish necessary development.

Do identical twins share the same placenta?

Some do, some don’t – it depends on when the egg splits to form the identical twins. If the egg splits within the first few days, they will have two separate placentas. If they egg splits after the first week, identical twins may share one placenta.
