not really. anyway, the whole typological model of the classification of "race" has been discredited. there are schools of thought which argue that there is no biological basis for a racial definition at all, "race" being a socio-political concept, whereas others argue that there
is a biological basis, based on epidemiological and immunological factors (e.g. predisposition and susceptibility to diseases - i'm thinking of sickle cell anaemia and hypolactasia, for example).
