The problem with inter-race donation is that the majority of people in different races have different blood and tissue types. But that is not to say that there are no donors available outside a given racial group. A mixed race person would inherit a blood and tissue type from either one or other of the parents and therefore the donor population for that person might be in the predominantly black or white race depending on his particular blood and tissue type.

This occasionally manifests itself when two white pare
