Identical twins

Definition

Identical twins are siblings that develop from a single fertilized egg that splits into two embryos, sharing the same genetic material. This unique origin results in identical physical characteristics and often similar psychological traits, making them a fascinating subject of study in various fields, including art and psychology. Their shared genetics can lead to discussions about nature versus nurture and how environment can shape identical individuals differently.
