For thousands of years farmers have used a process of selection and cross breeding tocontinually improve the quality of crops. Traditional breeding methods are slow, requiringintensive labor: while trying to get a desirable trait in a bred species, undesirable traits willappear and farmers must continue the process over and over again until all the undesirablesare bred out. In contrast, organisms acquire one specific gene or a few genes togetherthrough genetic modification, without other traits included and within a single generation.However, this technology too is inherently unpredictable and some scientists believe it canproduce potentially dangerous results unless better testing methods are developed.Traditional breeding is based on sexual reproduction between like organisms. Thetransferred genes are similar to genes in the cell they join. They are conveyed in completegroups and in a fixed sequence that harmonizes with the sequence of genes in the partnercell. In contrast, bioengineers isolate a gene frm one type of organism and collect itrandomly into the DNA of a dissimilar species, disrupting its natural sequence.One of the main differences between conventional and genetically modified crops is thatthe former involves crosses either within species or between very closely related species.However, GM crops can have genes from closely related species or even from bacteria andviruses. Benefits. one side of the debate Economical? GM supporters tell farmers that theystand to reap enormous profits from growing GM crops. It takes a shorter time to producethe desired product. It is precise and there are no unwanted genes. To produce the GMcrops, modern biotechnology is used which requires highly skilled people and sophisticatedand expensive equipment. Large companies need considerable investments in laboratories,equipment and human resources, hence the reason why GM crops are more expensive forfarmers than traditional crops.
