Question
What is the normal result if more than one egg is fertilized and there are multiple zygotes?
Solution
When more than one egg is fertilized and there are multiple zygotes, the normal result is a multiple pregnancy. This means that the woman will give birth to more than one baby at a time. The most common types of multiple pregnancies are twins (two babies), but there can also be triplets (three babies), quadruplets (four babies), and so on.
The type of multiple pregnancy can also vary. If each fertilized egg implants separately, the result is fraternal (or dizygotic) twins, triplets, etc. Each baby will have its own placenta and amniotic sac, and can be of the same or different sexes.
If a single fertilized egg splits into two or more embryos, the result is identical (or monozygotic) twins, triplets, etc. These babies share the same genetic material, are always of the same sex, and share a placenta and possibly an amniotic sac.
It's also possible to have a combination of these in a single pregnancy. For example, in a triplet pregnancy, there could be a set of identical twins (from one egg that split) and a third baby from a separate egg.
