Dominant and recessive traits in humans. 1  1. ï¨ There are over 200 traits that are transmitted from generation to generation in humans. These interesting aspects of human genetics are known as hereditary traits. 2  2. There are two or more variations in most ofthe genes called alleles.
As I said above, people have two versions of each gene so you can be BB, Bb, or bb--BB and Bb have brown eyes, bb, blue eyes. Versions of genes are often dominant because the recessive version actually does nothing (click here to learn about other ways that gene versions can be dominant).ominant means that one of the versions trumps the other. In our example here, brown is dominant over blue so you end up with brown eyes. The way people write out dominant and recessive traits is the dominant one gets a capital letter and the recessive one a lower case letter.
