Twins

Twins are two individuals born from the same pregnancy. They can develop from one fertilized egg that splits into two (identical twins) or from two separate eggs fertilized by two different sperm (fraternal twins). Identical twins share nearly the same genetic material and often look very similar, while fraternal twins are genetically similar to regular siblings and may look different. Twins can be born at the same time or within a short span, and their occurrence is influenced by genetic and environmental factors. Their unique bond is a fascinating aspect of human development.
