What are some of the social and ethical issues involved in genetic testing?

and any opinions on it?

This is probably one of the biggest ethical dilemmas out there in our current age...and there can be many issues, depending upon what kind of genetic testing you're asking about.

The most common thing people think of when you say "genetic testing" is in regards to pregnancy or parentage, things like amniocentesis or paternity testing. In the case of the former, whether it is ethical depends on who you ask. There are many who think it should be within a parent's right to decide whether they want to raise a child with a disability, and many who think it's inherently wrong to decide whether someone else should get the chance to live based upon another's perceptions of what their life will be like. Personally I think it is stepping out of bounds if a child is found to have a treatable condition or one that won't tragically shorten their life...for instance Down syndrome, an abnormality of the sex chromosomes, or some nonlethal forms of dwarfism. If something is discovered that will cause a baby to die either in utero or very shortly after birth, then that is a whole different story...there are many genetic syndromes that will cause this situation, and in that case, if one is discovered, then termination should be offered as an option without passing judgement on the parents. (After all, is it ethical to force parents to watch a child suffer and die a painful death? I would think not.)

As for paternity testing, it is certainly within a mother's right to know who her child's father is. It doesn't say much for someone if they don't already know who the father is, or if that father doesn't accept responsibility...but legally it is usually a binding result: if the testing proves paternity, then the man has to own up to his responsibility.

The other worry is that employers and insurance companies will employ genetic testing to screen for the health of any potential employees or clients, and then refuse people based upon any negative information that's discovered. That, IMHO, is completely UNethical. Whether a person has the potential to develop a particular disease should not be the way to screen out...that's called putting money before human decency, and that's just plain, flat out wrong. You should not be able to effectively punish someone because they come from "bad stock"...that smells eerily like what Hitler was trying to do with the Holocaust, obviously a road humanity doesn't want to go down again.

Hope this answered your question....

genital heritage , such as hair color hair type eye color ...genital testing such as blood tests DNA and DNS testing and more but just to make sure, as your doctor

I would think that one of the main issues would be if during pregnancy genetic testing found the fetus to have an inherited disease. Does one then have an abortion or continue with the pregnancy.

Also, how would this informaiton be used. It could be used to keep someone from getting medical insurance, jobs, etc.
