>>281271928I'm not sure what you're highlighting. Ripple has B type same as her Mother. Dad has A type, Lil bro has O type.
Since blood type is inherited and A and B are both dominant this is possible if both parents have an A and an O allele.
So Dad is AO
Mom is BO
Dad passed O to Minamo while Mom passes B.
Both pass an O to son to make him O.
Pretty sure we've known the girls and villains blood types for awhile now.
