Biologically Impossible
Mating between a horse and a human would never result in a centaur.
Reasons
- Species are too different: Vastly different genetic makeup makes DNA incompatible.
- Chromosomes: Horses have 64 chromosomes; humans have 46. They cannot pair correctly for fertilization and development.
- Developmental incompatibility: Even if fertilization occurred, the embryo could not develop properly due to biological differences.
The centaur is purely mythical and not grounded in biological reality.
