Mirror twins, also known as monochorionic dizygotic twins, are identical individuals who develop in separate uteruses. This phenomenon occurs due to genetic abnormalities that involve gene duplication, mutation, or chromosomal imbalances. Mirror twins share 100% of their genetic material but exhibit unique physical and developmental characteristics, including craniofacial asymmetry, neural tube defects, and potential developmental differences. The psychological and social implications of mirror twinhood include challenges with identity formation, sibling rivalry, and social integration. Ongoing research and support initiatives aim to provide comprehensive care and understanding for these remarkable individuals.
