I really doubt genetics has anything to do with the lack of popularity of football and basketball in the vast majority of the world. The actual probable reason is equipment. If you’re playing a tackle sport why would you choose a complicated one such as football over rugby? And basketball requires the installation of a net, a good flat surface and a high quality ball that bounces well off the ground. Soccer on the other hand can be played with basically anything.
