(N/A) Advantages :
$(i)$ Knowledge about the effects of $DNA$ variations among individuals can lead to revolutionary new ways to diagnose,treat,and someday prevent thousands of disorders that affect human beings.
$(ii)$ Besides providing clues to understanding human biology,learning about non-human organisms' $DNA$ sequences can lead to an understanding of their natural capabilities that can be applied toward solving challenges in health care,agriculture,energy production,and environmental remediation.
$(iii)$ Deriving meaningful knowledge from $DNA$ sequences will define research through the coming decades,leading to a deeper understanding of biological systems.
$(iv)$ Scientists can study all the genes in a genome,for example,all the transcripts in a particular tissue,organ,or tumor,or how tens of thousands of genes and proteins work together in interconnected networks to orchestrate the chemistry of life.
Disadvantages :
$(i)$ It creates ethical and legal problems regarding the patenting of genes.
$(ii)$ Individuals might become careless about their health or lifestyle choices based on genetic predictions.
$(iii)$ People may misuse or abuse the sensitive genetic information obtained from the $HGP$ for discrimination.
