Since the antigens are closely linked to race and ethnicity, it is much easier to find a biological match among people with similar ethnic and racial backgrounds than it is among any two randomly selected individuals. On the basis of tissue matching, organs from blacks will almost always go to blacks and organs from whites will almost always go to whites. Blacks, however, have a much higher incidence of kidney failure than whites. But since whites significantly outnumber blacks in the American population, there are still large numbers of whites waiting for organs. There are so many, in fact, that nearly every white donor is matched to a white recipient. Blacks and other minorities must rely on a much smaller pool of kidneys. The situation for potential black kidney transplant recipients is made even worse by the fact that blacks have a lower rate of cadaver organ donation than do whites. So there is a disproportionately small share of black cadaver kidneys available for a disproportionately large group of blacks in need of kidney transplants. By deciding to use biology in the name of efficiency and, it must be added, fairness, whites wind up with a much larger number of kidney transplants than do blacks relative to the incidence of renal failure in both groups. (Caplan, p. 33-34).
The HGP can impact race in a non-medical way as well. Currently, members of ethnic groups either self-identify or are identified by others due to physical markers or characteristics. For example, in America, a dark skinned person with certain features, such as thicker lips or kinky hair, is presumed by people to be African-American and is treated like an African-American, regardless of actual genetic heritage. However, people may actually not have the genetic heritage to support an existing racial or ethnic identity, which begs the question: "Should knowledge generated by the genome project be used to identify, classify, or label racial or ethnic groups or to establish the boundaries of their membership?" (Caplan, p.40). Furthermore, if people are screened or selected for race, should genetic/biological definitions be used or will cultural and political definitions prevail? (Caplan, p.40). If genetic definitions prevail, then it is likely that people who culturally identify with certain races will be excluded from those classifications because DNA studies have not revealed classifiable races in modern humans; though some alleles are more highly identified with certain subgroups of people, some members of those subgroups will not have those alleles, and some people outside of those subgroups will have those alleles.
The largest ethical issue related to the Human Genome Project is the looming specter of human cloning. While the cloning of an entire human being may be impossible anytime in the foreseeable future, and animal clones have repeatedly had some health issues that were not present in the original animal, the idea of human cloning is more of a grey area than opponents would have one believe. After all, cloning does not have to be of an entire person. In fact, proponents of cloning rarely suggest that one should clone an entire person. On the contrary, they suggest that cloning would be appropriate to replace single failed organs, because a cloned organ would not be rejected in the way that donor organs are rejected.
Legal Concerns
One interesting legal issue is whether the state could require or, conversely, prohibit certain types of genetic testing. For example, some genetic conditions make a person far more susceptible to certain disease; should the government be allowed to require people to get those tests? It is unlikely that the government would ever require every individual to submit to random genetic testing, but there are certainly situations where other stakeholders might want to insist upon mandatory testing. For example, the costs of preventative medicine are often considerably lower than the costs of treatment. Therefore, it is imaginable that insurers might push for mandatory genetic testing, so that they could deny coverage to those who did...
