What are some non-polygenic traits? 10 points?!?

A polygenic trait is a trait controlled by two or more genes. Some polygenic traits include eye color and hair color but I need to know some non-polygenic traits, so traits that are controlled by only 1 gene. two non-polygenic traits are ear lobes and blood types but I need more examples. Please help! I don't know what else I can do and my project is due soon!

    If you're looking for fairly common human traits controlled by a single gene, there is also tongue rolling, hitchhiker's thumb, widow's peak, PTC tasting, etc. Take a look at the article.
