I have white forelock hair (Dominant trait) from my mom’s genes. My dad doesn’t have white forelock hair. If I were to have no white forelock hair, it would be a Recessive trait.

I probably don’t have any dimples (Recessive trait) because my father does not have any. My mom does though, so I must have no dimples because of my dad. The null trait of having no dimples is to have dimples (Dominant trait), which means you have little dents around your mouth.

I have no mid-digit hair (Dominant trait), and my father doesn’t either. This means that I got those genes from him. The null trait of this is having mid-digit hair (Recessive trait).

I have a straight pinky (Recessive trait). My dad also has a straight pinky, so I got these genes from him. The opposite of having a straight pinky is a bent pinky (Dominant trait).

I have free earlobes (Dominant Trait). My mom and dad both have free earlobes, so I definitely got these genes from my parents. The opposite of my free earlobes are attached earlobes (Recessive trait), which, hence it’s name, means that the ear lobes are attached to your skin instead of just hanging.

I have a Curved thumb (Recessive Trait) because my both my mother and father can do it, so I clearly got those genes from them both. The null trait of a Curved thumb is a straight thumb (Dominant Trait), where you can’t bend it.

I have a longer first toe than my second toe, and the only person in my family that has this is my grandpa. So I must have skipped a generation and gotten some of those genes from him.

I can roll my tongue (Dominant trait). If would not be able to roll my tongue, it would be a Recessive trait.
