Barbara is homozygous for the dominant trait of having curly hair.
Explanation:
Generally, capital letters refer to dominant traits.
Therefore, I know that curly hair is a dominant trait (in this case).
In addition, I see that Barbara has two genes for curly hair, thus, she is homozygous.
If Barbara is homozygous, then both her parents have curly hair. We don't know if her parents are also homozygous.
Hope this helps :)
