A human life is so valuable that no single price should be placed on it. The effect on this stance on bioethical issues however, is relative.
<h3>Relativity of Human value to Bioethical issues</h3>
- A person's stance on a bioethical issue can be based on which human life they value more, the person that will gain, or the one that will be affected.
- With abortion, one might argue that the value of the mother is higher than the baby's because not having to take care of a child will give her a better life.
- Designer babies might be more valuable because their lower rate of birth defects mean that they are tougher and less expensive to maintain.
- Stem cell research could save many lives so more value might be placed on these lives than the embryos affected.
In conclusion, a person can see another life as valuable yet have relative views on bioethical issues.

Answer:
geographical isolation
Explanation:
Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.
There are two mechanisms of reproductive isolation:
- Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation, geographical isolation and behavioral isolation.
- Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.
<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>
