Mosquito Attraction and Genetics

The video explores why mosquitoes are more attracted to some people than others, highlighting genetic factors. Supported by 23andMe, the video includes an experiment with Professor Immo Hansen to test mosquito attraction. Genetic analysis reveals specific DNA locations linked to mosquito attraction. The video discusses the significant health impact of mosquitoes, including malaria, and considers whether humans evolved to be less attractive to mosquitoes. The video concludes with a sponsor message from 23andMe.
