Question

what is one benefit of mapping the human genome?
locating the chromosomal abnormalities that cause disease
having the genomes of every living individual on file
choosing the gender or intellectual ability of an unborn child
cloning the individuals that comprise a nearly extinct tribe

Explanation:

Mapping the human genome helps in understanding genetic - related diseases. By knowing the normal genome sequence, chromosomal abnormalities causing diseases can be located. Having every individual's genome on file is unethical and not a practical benefit. Choosing gender or intellectual ability of an unborn child is unethical. Cloning individuals of a nearly - extinct tribe is not a benefit of genome mapping.

Answer:

locating the chromosomal abnormalities that cause disease
