“Triplets” refers to three siblings born at the same time, typically from the same pregnancy. Just like twins, triplets can either be identical (originating from a single fertilized egg that splits into three embryos) or fraternal (coming from three separate eggs fertilized by three different sperm cells).
Identical triplets are rarer than fraternal ones. Each set of triplets can have its own unique characteristics, even if they share the same birthday!
Are you asking about triplets in a specific context—like a story, family situation, or something else?
