Which advantage of genetic technology would be most
helpful in solving this problem?
In recent years, a certain area of the world has
experienced greater shifts in weather patterns. For
example, there are many nights during which the
temperature gets below freezing, but many days that are
very warm. These shifts have made it difficult to grow
and harvest crops.
O increased nutritional value of crops
increased resistance to environmental factors
greater resistance to crop-killing diseases
greater resistance to insecticides
O

Explanation:
Genetic engineering made it possible to create crop varieties regarded as “more beneficial”. Unlike selective breeding, modern genetic engineering is more gene-specific. One of the downsides of selective breeding is the possibility of generating traits that are less desirable. This is averted by modern genetic engineering that introduces specific genes. (Ref. 1) Since the process is rather straightforward, it is relatively faster than selective breeding (see previous tutorial) in terms of coming up with crops with the desired traits. Examples of genetically-engineered plants with more desirable traits are drought-resistant plants, disease-resistant crops, plants that grow faster, and plants (e.g. legumes) fortified with more nutrients. (Ref.1, 2) The latter may be achieved by introducing genes that code for (1) trace-element-binding proteins, (2) overexpression of storage proteins already present, and/or (3) increased expression of proteins that are responsible for trace element uptake into plants. (Ref. 2)
Organisms can be ‘tailor-made’ to show desirable characteristics. Genes can also be manipulated in trees, for example, to absorb more CO2 and reduce the threat of global warming. Through genetic engineering, genetic disorders may also be fixed by replacing the faulty gene with a functional gene. Disease-carrying insects, such as mosquitoes, may be engineered into becoming sterile insects. This will help in curbing the spread of certain diseases, e.g. malaria and dengue fever.
Genetic Engineering could increase genetic diversity and produce more variant alleles that could also be crossed over and implanted into other species. It is possible to alter the genetics of wheat plants to grow insulin as an example.Nevertheless, there are two sides to a coin. While genetic engineering is beneficial in ways mentioned above it is also implicated in certain eventualities deemed as “unpleasant” or disadvantageous.
There are concerns over the inadvertent effects, such as the creation of food that can cause an allergic reaction, GMO that can cause harmful genetic effects, and genes moving from one species to another that is not genetically engineered. (Ref. 1) It has been shown that GMO crop plants can pass the beneficial gene along to a wild population. An example is the sunflowers genetically-engineered to fend off certain insects. They were observed to have transferred the gene to their weedy relatives. (Ref. 3) Nature is an extremely complex interrelated chain. Some scientists believe that introducing genetically-modified genes may have an irreversible effect with consequences yet unknown.
Genetic engineering borderlines on many moral and ethical issues. One of the major questions raised is if humans have the right to manipulate the laws and course of nature.
