Many foods that we eat today have been genetically altered, such as potatoes, corn, tomatoes, rice, and tobacco. Potatoes are transgenic crops that carry genes from different sources. One gene they receive is from chicken. This genetic change increases the potatoes resistance to diseases that affect potatoes. Another gene they receive is from bacteria, which causes a greater habitat tolerance.
Potatoes can resist harsh, cold weather.
A third gene source that alters potatoes comes from the greater Wax-moth. This alteration increases the potatoes resistance to bruising damage that occurs before people eat them. Other non-related genes that are transferred to potatoes come from the Giant Silk moth and a virus, which again provide potatoes with an increased resistance to diseases. Corn is another genetically altered crop. It does not have as many new genes transferred into it as potatoes do.
