Triplets

Triplets

Triplets (/ˈtrɪplɪts/) are a set of three offspring born at the same time from the same pregnancy. They can be the same (monozygotic) or different (dizygotic) genetic types.

Etymology

The term "triplets" comes from the Latin word "tripletus", which means "threefold" or "three at a time".

Types of Triplets

There are three types of triplets:

• Monozygotic Triplets: These triplets are formed when a single fertilized egg splits into three. They are genetically identical and are always of the same sex.

• Dizygotic Triplets: These triplets are formed when three separate eggs are fertilized by three separate sperm. They can be of the same sex, different sexes, or a combination of both.

• Trizygotic Triplets: These triplets are formed when a combination of monozygotic and dizygotic fertilization occurs. This can result in triplets who are a mix of identical and fraternal.

Related Terms

• Fraternal Twins: Two offspring from the same pregnancy who are dizygotic, meaning they were formed from two different eggs fertilized by two different sperm.
• Identical Twins: Two offspring from the same pregnancy who are monozygotic, meaning they were formed from a single egg that split into two.
• Pregnancy: The period of time during which one or more offspring develops inside a woman.
