Which passage from the article best supports the idea that sunny sneezes are inherited? The genetic nature of the condition is reflected in its alternative name, autosomal-dominant compelling helio-ophthalmic outburst syndrome. Scientists theorize that the electrical signal traveling through the optic nerve gets picked up by the trigeminal nerve as well. When the trigeminal nerve senses irritants such as dust or pepper, in your nose, it sends a message to your brain, and you sneeze to expel the troublesome stuff. Even today, however, scientists aren't entirely sure what causes it, partly because medical researchers focus a lot more attention on harmful diseases than sunny sneezes.
