 Questions and concerns have also been raised regarding the appropriateness of selection on the basis of characteristics related to ‘race’, such as skin, eye, and hair colour. Had gamete donor selection been well known in the 1980s when discussion raged concerning whether trans-racial adoption practices constituted a step in the right direction towards the social ideal of colour-blindness, a form of racial and cultural genocide, or something in between the two, one might have expected to see similar discussions regarding donor selection. This, however, has not been the case and instead, the philosophical literature on race-based selection has tended to focus on the question of whether selection of race-based characteristics is appropriate at all.
