I'm sure Taiyang is the one with blonde hair, since the woman in the photo Yang showed Junior had dark hair. Or maybe both Taiyang and Yang's mom carry the blonde gene but don't have blonde hair. After all, two parents with black hair can birth a child with blonde hair in real life.

Genetics are not as simple as "Both parents have black hair, therefore the child cannot have blonde hair." That's like saying "Both parents have brown eyes, therefore the child cannot have blue eyes." Recessive genes stay in the parents, but do not present themselves as physical features. However, if both parents carry the recessive gene, and the DNA that comes together from their contributions contains that recessive gene from both parents, it will result in a physical feature in the child.
