Give an example of a trait that is controlled by more than on gene. i don't understand the question who can me .

Polygenetic inheritance is the term for traits that are controlled by more than one gene...
Examples of this is ones height, skin, hair color and eye color...

I may need more information on the types of genes you are talking about. If it is something about, say, you love to read, it may be because you dad and you uncle love to, or mom and dad or something. That is what it seems you are implying, but if you are talking about specific gene types here, I will need you to specify. Thanks though :D
