Answer:

The blond hair was a result of the expression of a recessive gene.

A gene is a basic unit of hereditary information that influences a particular trait or group of traits. Blonde hair is a recessive trait that can be expressed if both parents carry the gene for blond hair and both of those genes are inherited by a child.
