Conjoined Twins Prove Life’s Crazier When You’re Stuck Together 24/7

The Unique Biology of Conjoined Twins

Exploring the world of twin biology uncovers some captivating details. Identical twins form when a single egg splits into two embryos, producing two nearly identical individuals. However, in the case of conjoined twins, the egg begins to divide but doesn’t fully separate, resulting in children born physically connected.

Twins may be identical or fraternal, yet conjoined twins are always identical, sharing nearly the same genetic makeup. While fraternal twins can differ in gender, conjoined twins are always of the same gender, with a significant majority being female. This unique phenomenon continues to intrigue scientists and the public alike, offering rare insights into human development.
