The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that since this has never been done before, we should probably not do it now. c) that employers may discriminate against people who have genes linked to certain illnesses. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.

The correct answer is option C.

Human genome project is devoted in mapping the DNA sequence and the the ethical issues that is related to this project is that the employers might deny to work with the people having certain kind of illness in their body that is associated with the genes. The people working together might discriminate the person having illness.

This is the reason that the data is kept confidential.

Option C, that employers may discriminate against people who have genes linked to certain illnesses.

Explanation:

Though the objective of human genome project is to advance clinical and scientific investigation on 3 billion base pairs exiting in human beings, experts have raised concern over the data & information secrecy and ethical issues associated with it.  

One of the major issues is associated with the discrimination based on the genetic history or any prevailing genetic disease in family. The insurances companies may not provide medical insurance to such people or families who have a genetically diseased background. However, in present time these insurance companies limit their benefits to an individual or family with medical history. Also, there can be cases of job discrimination at workplace or discrimination at place of accommodation by the local residents etc.  

Hence, option C is correct

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
