Barbara has curly hair. Her genotype for this trait is CC. What do you infer from this?
Barbara is homozygous for the dominant trait of having curly hair.
Capital letters typically denote dominant characteristics.
I am aware that curly hair is a dominant trait because of this (in this case).
Furthermore, I see that Barbara is homozygous for curly hair because she carries two genes for the trait.
Barbara's parents may not be homozygous, but if they are, then both of them will have curly hair.
I hope this is helpful.

Barbara's genotype for the trait of curly hair is homozygous dominant (CC). This means that both of her alleles for the gene associated with hair texture are the dominant allele, which in this case determines curly hair. Therefore, Barbara will express the trait of curly hair.
