Bioengineering in Food - Research Paper Example 262). Hybridization, on the other hand, refers to the process of cross-breeding genetically dissimilar crops, both within and between species (Aheto, 2008, p. 77). Genetic engineering and hybridization differ in origin: genes from genetic engineering originate from any living organism, virus, or even chemical synthesis while genes from hybridization may originate from genetically different plant genera and families. Genetic engineering enabled food and crop scientists to manipulate the DNA of plants at molecular level. It has allowed possible transfer of DNA between two distantly species, unlike the traditional hybridization. Organisms that have been transformed using genetic engineering are often called transgenic organism, genetically engineered organism, or genetically modified organism (Wieczorek, 2003, p. 1); hybrid is the term used for organisms that underwent hybridization. The major differences of genetic engineering and hybridization in agriculture are noticeable in terms of results and economic impact. No matter how good the breeder is in choosing the best parents to cross or hybrid, the result is still unpredictable in the genetic levels. DNA of parent crops recombines randomly and may exhibit desirable traits such as pest resistance but the hybrid may also exhibit undesirable traits such as poor quality and lower yield. Because of the possibility to produce a crop which has undesirable characteristics and the great deal of effort required to separate undesirable from desirable traits, hybridization or traditional breeding is time-consuming, labor-intensive, and is not economically practical. Meanwhile, genetic engineering is economically practical as it allows segmentation of specific characteristics of DNA to be selected and removed unwanted traits, making the desired gene controlled, precise, and of high quality (Wieczorek, 2003, p. 1). Advantages of Bioengineering Wieczorek (2003) identified a few examples of benefits or advantages of bioengineer ing to the agriculture, among of which are: increased crop productivity, enhanced crop protection, improvements in food processing, improved nutritional value, better flavor, and fresher produce (p. 2-3). Genetically engineered crops increased crop productivity because it introduced qualities such as disease resistance and increased drought tolerance to the crops (Wieczorek, 2003, p. 2). Examples of which are the cases in University of Hawaii and Cornell University that developed two varieties of papaya resistant to papaya ringspot virus. The used of genetic engineering in agriculture has also increased crop productivity by developing drought-resistant plants that are capable of using water efficiently. Genetic engineering also enhanced crop protection and can make cost-effective solutions to pests’ problems (Wieczorek, 2003, p. 2). The research from the soil bacterium Bacillus thuringiensis has made protein in the crops such as corn, cotton, and potato into a protein that ki lls certain insects when they feed on the plants. This technological breakthrough is also the protein used in natural insecticides. The similar case applies to Bt engineered into a corn crop, making pest control more cheaply, more effective, and less expensive, but Bt crops are considered inacceptable because the entire

Qustions - Essay Example Franchising can also generate high financial returns for relatively little risk since little money is put into each location. Franchise business model leads to lesser control over managers since the franchisees cannot be controlled as employees. Franchisees are independent businesses with different goals from the owner that may eventually lead into legal troubles. It is also not easy to get franchisees compared to hired store managers to work together and the franchisees obtain incentives to profit from each other’s efforts to generate business. There are also innovation challenges associated with franchising since when an individual comes up with an idea, there must be a negotiation with other franchisees to accept the innovation. Porter’s Five Forces technique is a very significant tool, which attempts to point out at some of the significant strength in every business situation. These forces help in identifying some of the competitive intensity as well as overall industry profitability. The Porter’s tool highlights competition from both external and internal sources. The strengths identified by the Porter’s tool may help a business to understand her strength in the competitive position as well as the strength of a place or step that the business wants to make. It is therefore clear that by identifying strength position, business can take fair advantage, eliminate wrong situations and eventually creating sustainable advantage. Supplier power is one of the important forces, which help business to determine ease of driving up prices by the suppliers. Business may counterbalance this force by standardizing specifications in parts for it to change among suppliers easily. Business may decide to add more vendors or even change technology to eliminate coming together of strong suppliers. By standardizing specifications, adding more vendors, and
