My baby is around two years old now . he has very light color golden hair since his birth. Both the parents have black coloured hair. what could be the reason behind this?

A. Mam there is no specific reason to it but it is natural sometimes the hair of the child could be different though I understand the parents have black hair only but it is not only based on the genetics of the parents it’s on the stream of the other side so maybe in your family stream somebody had this kind of hair previously
