Someone ! our understanding of dna and gene expression has dramatically increased over the last 50 years. describe 2 positive impacts and 2 negative impacts that the field of biotechnology and genetic engineering has had in agriculture, medicine, and human health?

By understanding DNA and gene expression, humans have been able to understand how genetic diseases are caused, therefore they have been able to devise gene therapy and other technologies to treat such disease. Second, the understanding has also allowed humans to devise plants that are resistant to pests and drought hence increasing crop yields.

A negative aspect of this understanding is the issue of bioterrorism. In the wrong hands, this technology can be used against society. The technology can be used to modify organisms to make them deliberately harmful to humans. Second is the issue of bioethics. This technology can be used to enhance humans and result to an ‘arms race’ between human races that can tear down the social fabric.

it will increase due to the time span

i believe it is c: genes for body color and wing size are inherited separately from each parent.
