@Val_Aljajawi If any ancestor from ur mom or dads side had red hair, then yes there is a possibility. But, traits can also be lost over generations either by mutations or non-expression. So to answer ur question... yes BUT it depends. If u want to look more into it search about punnett square
@Val_Aljajawi if you and your spouse both have let's say black hair but happen to be carriers of the ginger gene, then there is a probability that your offspring can be ginger. if they aren't, then their kids can be because they may be carriers as well...and so on and so forth. kapeesh?
@Val_Aljajawi mutation is a possibility (not necessarily sporadic b/c that mostly deals with diseases) but most likely it has to do with heredity. if you have an ancestor that was ginger, there is a chance next generations can be ginger as well since traits get passed from parent to offspring.
