TED-Ed: Sex determination: More complicated than you thought - Aaron Reedy

The video explores various sex determination systems across the animal kingdom. It begins with the human XY chromosome system, explaining how sex is genetically determined. It then discusses other genetic systems in mammals, birds, and reptiles, highlighting differences like the ZW system in birds. The haplodiploid system in insects like ants and bees is explained, where males have no fathers. Environmental factors, such as temperature, determine sex in reptiles and some fish. Unique systems in clownfish and spoonworms are also covered. The video concludes by emphasizing the diversity of sex determination systems.
