Psychology Question
The time is coming when choosing the genetic traits of your child is going to be possible. What kinds of ethical and practical problems may arise from this development.

Respuesta :

Explanation:

Ethical doubts about genetic engineering motivate a view that many philosophers favour: that genetic therapy to eliminate disease and disability is ethically acceptable, given that the risks can be overcome.

But genetic enhancement is ethically problematic. The line between enhancement and therapy is difficult to draw.

Studies show people who are physically attractive are likely to earn more than those considered to have below-average looks. Does this mean “ugliness” is a disability that ought to be corrected by genetic engineering?

Or, similarly, is having a below-average IQ a disability, something that should be subject to change through gene-editing?

In humans, new technologies could result useful to prevent and/or cure specific diseases, but genetic selection based on 'desired' phenotypic traits (e.g,  eye color) is not ethical and may increase human inequalities.

During the last years, the development of new genome engineering tools and especially, the development of the CRISPR-Cas9 system, which can be used as a genetic scissor capable of inserting any desired gene sequence in an organism, have made possible the design of new organisms with different phenotypic features.

In the near future, genome editing might result very useful to cure and even prevent inherited diseases.

However, this situation also raises serious ethical concerns because virtually any phenotypic human trait can be modified in the germline by designing genetically modified babies with 'desired' phenotypic characteristics.

In consequence, genome editing technologies should be used with caution because they may increase human inequalities (for example, by designing babies with higher cardiovascular endurance) or may have unethical motives (for example, by modifying natural phenotypic traits such as eye color, hair color, etc).

In conclusion, in humans, new technologies could result useful to prevent and/or cure specific diseases, but genetic selection based on 'desired' phenotypic traits (e.g,  eye color) is not ethical and may increase human inequalities.
