Heredity And Traits

On this site I learned about Heredity and Traits. First Heredity is what we inherit from our parents for example our height color eyes and color hair are Heredity. For Traits I learned about our thumbs when a baby has a hitchhikers thumb both of the parents have it because it is the weaker Trait. A regular traight thumb is the dominant trait and if one parent has a hitchhikers and the other has a regular thumb the baby will come out with a regular thumb.
