 Yet despite the distinction generated between different races, Kant’s monogenetic account led him to maintain that the different races were part of a common human species. As evidence, he adduced the fact that individuals from different races were able to breed together, and their offspring tended to exhibit blended physical traits inherited from both parents. Not only did blending indicate that the parents were part of a common species; it also indicated that they are of distinct races. For the physical traits of parents of the same race are not blended but often passed on exclusively: a blond white man and a brunette white woman may have four blond children, without any blending of this physical trait; whereas a Black man and a white woman will bear children who blend white and Black traits (Bernasconi and Lott 2000, 9–10). Such inter-racial mixtures accounted for the existence of liminal individuals, whose physical traits seem to lie between the discrete boundaries of one of the four races; peoples who do not fit neatly into one or another race are explained away as groups whose seeds have not been fully triggered by the appropriate environmental stimuli (Bernasconi and Lott 2000, 11).
