If black hair is dominant, why am I blonde?

Question

My mother has had blonde, wavy hair all her life and my dad currently has black, curly/wavy hair--depending on the length. However, my mom has told me that he had lighter hair when he was young. He does not dye it. How is this possible? And if he has dark hair, should I not have dark hair as well? Will my hair eventually become dark like my dad's? Just a side note; I'm not adopted.

Also, my birth parents divorced and my mom married this man with black, curly hair, but when they had a son, he had blonde hair like mom's! He is five years old now, and he still has the same blonde hair. How is this possible??

Your dark haired father must have some recessive allele gene that encodes blonde genetics. I guess his faded away with time. The only way for you to have blonde if your father has a recessive blonde gene and your mother having a recessive blonde gene. If you father had given you a dominant black haired gene, then you would have had darker hair. And it seems your did not pass that gene to you, but he did pass the blonde one. His parents or grand parents are grand grand parents must be blonde too

The reason why is everyone with blond, why cannot you just have jet black curly hair with some blonde or blonde curly hair with some jet black hair. Now you don't have to choose.

Blond would really suite you in my opinion. It looks really pretty as well as it has a style that's really noticeable. You'd look good with it.

It means that your black haired father must have had at least on light haired parent.
