If one is a firebender, one must have Fire Nation blood. If one is an earthbender, one must have Earth Kingdom blood. That is fact.

Since one brother is an earthbender, and thus must have EK blood, while the other is a firebender, and thus must have FN blood, then their family has at least two different races, which makes the family multiracial.
