An understanding of genetics an lead to new fields of healthcare, treatment, and earlier/more trustworthy diagnosis, because 1). it would allow scientists to see which genes in people with certain diseases are common, and then identify those genes in other people to help them get treatment, 2). this would lead to further research into the field of genetics, and (hopefully) eventually lead to scientists identifying genes that correlate with certain diseases/afflictions, and then help people find treatment/somehow prevent these diseases from occurring in the future, and 3). this would give allow scientists to help develop new treatments/medicines for certain gene-based diseases.
Hope this helps!
