Genetics

             What does it mean when a food product is genetically modified? Describe 3 characteristics of the food that may be modified (i.e, what do they change about the food?)
             When a food product is genetically modified, it means that in a laboratory plants or animals have been modified to enhance the most desired traits. These kinds of plants are called GM crops or genetically modified crops. These traits include such things as increased resistance to herbicides, or improved nutritional content. When doing this scientist use direct modification to DNA. In other words, Genetic engineering creates plants with the exact desired trait, with good accuracy. Like seedless watermelons or seedless grapes.
             Some characteristics of the food that may be modified include size, solids content, or resistance to certain viruses or fungi.
             List and explain 4 advantages of genetically modified food products.
             There are many advantages to genetically modified foods. Whitman writes one advantage would be Herbicide tolerance. For some crops, it is not cost effective to remove weeds by physical means such as tilling, so farmers will often spray large quantities of different herbicides (weed killer) to destroy weeds, a time-consuming and expensive process, that requires care so that the herbicide doesn't harm the crop plant or the environment. Crop plants genetically engineered to be resistant to one very powerful
             herbicide could help prevent environmental damage by reducing the amount of herbicides needed.
             Whitman also writes that another advantage would be Disease resistance. There are many viruses, fungi and bacteria that cause plant diseases. Plant biologists are working to create plants with genetically engineered resistance to these diseases
             Another advantage as stated by Whitman would be drought tolerance and salinity tolerance. As the world population grows and more land is utilized for housing instead of food production, fa...
