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 identifying chromosomal abnormalities related to diseases. Having every individual's genome on file is unethical and impractical. Choosing gender/intellect of an unborn child through genome mapping is unethical and not a valid scientific use. Cloning nearly - extinct tribe individuals is not a benefit of genome mapping.

Answer:

locating the chromosomal abnormalities that cause disease
