Memes versus genes - another observation

Is one of the indications of the success of memes replacing genes the evolution of organizations to become more tolerant of non-genetic relationships? For example, the move from societies based on genetic (tribal) relationships to societies based on memetic relationships. Is this an explanation for the reduction of genocide as a means of organizational selection? Does the value of non-genetically related human beings versus the value of genetically related human beings depend on the social organization of the human beings? Is the value of a non-genetically related species different from the value of genetically related species? What other examples of genetic-based values are present in all or most organizations? Are these genetically-based values stronger in more genetically-based organizations?
