This image shows the comparison of a normal cow and a genetically modified cow through selective breeding.
The genetic modification may be either through manipulation of genes (genetic engineering) or as a result of traditional animal and plant breeding methods like selective breeding or cross-breeding between organisms within the same species.
This phenomenon could stimulate the following driving questions:
1. How are these two cows different? How are these two cows the same?
2. What are possible causes of these differences?
3. What would be the benefits of the cow on the right?
4. What is the impact of modifying a cow or any other organism?
