Scientists in recent years have been able to move any gene, whether it is from an animal, plant, or even bacteria to any type of crop. Butterflies and daffodils for example are used in bioengineering for their yellow traits. The transferring of these genes changes a crops color, size, and tolerance to cold or frost. It also helps make crops harm free from insects and insecticides. 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.
