|
What effect does the presence of glyphosate-resistant crops have on insect populations in adjacent fields?
|
|
|
Is it possible for the gene for resistance to glyphosate to pass from the crop plants to weeds under natural conditions?
|
|
|
Does the genetically modified crop produce yields that are better in quality and quantity than those of unmodified varieties?
|
|
|
Is the gene for resistance stable enough in the crop plant that it will be passed to the next generation when the crop plant reproduces?

Detailed explanation-1: -All of these products of genetic engineering were created using the same basic steps: identifying a trait of interest, isolating that genetic trait, inserting that trait into the genome of a desired organism, and then growing the engineered organism (Figure 1).
Detailed explanation-2: -The Human Genome Project (HGP) was an international 13-year effort, 1990 to 2003. Primary goals were to discover the complete set of human genes and make them accessible for further biological study, and determine the complete sequence of DNA bases in the human genome.
Detailed explanation-3: -Pigs offer advantages over primates for organ procurements, because they are easier to raise and achieve adult human size in six months. Pig heart valves are routinely transplanted into humans, and some patients with diabetes have received porcine pancreas cells.
Detailed explanation-4: -With this ability to make deadly pathogens resistant to modern medicine, genetically engineered organisms become lethal weapons that cannot be stopped. Other than lethal weapons, genetically engineered organisms can produce lethal chemical compounds when they are used as a manufacturing tool in the chemical industry.
