Answer :

advantages :

1. Disease could be prevented by detecting people/plants/animals that are genetically prone to certain hereditary diseases, and preparing for the inevitable. Also, infectious diseases can be treated by implanting genes that code for antiviral proteins specific to each antigen.
2. Another of genetic engineering is that diseases could be prevented by detecting people that are genetically prone to certain hereditary diseases, and preparing for the inevitable. As well as preventing disease, with genetic engineering infectious diseases can be treated by implanting genes that code for antiviral proteins specific to each antigen
3. Animals and plants can be 'tailor made' to show desirable characteristics. Genes could also be manipulated in trees for example, to absorb more CO2 and reduce the threat of global warming.
4. Genetic Engineering could increase genetic diversity, and produce more variant alleles which could also be crossed over and implanted into other species. It is possible to alter the genetics of wheat plants to grow insulin for example.
5. Another advantage of genetic engineering is that animals and plants can be made to have desirable characteristics which could help solve some of the world's problems. For example in trees, genes could be manipulated to absorb more carbon dioxide. This would help reduce global warming, and thus solve one of the biggest problems earth faces.

Certain genetic diseases could be prevented.
