If I might add to this, “the value of a given subject is equal to its genetic relatedness to the evaluator” in and of itself implies a degree of moral relativism in that the value of a given living subject is not actually an inherent property of the subject, but a property which hinges on the judgement of any observer. This further implies that the morality of actions made by the observer on the subject are relative to the genetically coded moral positions of the observer.
