What is a common outcome of genetic engineering in animals?

The production of desirable traits is a common outcome of genetic engineering in animals. This process involves manipulating an organism's genetic material to enhance or introduce specific characteristics that are beneficial for various purposes, such as improving health, increasing growth rates, or enhancing resistance to diseases. For example, scientists may insert genes associated with desirable traits, such as better muscle development in livestock or greater resistance to environmental stressors in laboratory animals. This targeted approach allows for precision in achieving specific outcomes that can improve the productivity or utility of the animals involved.

In contrast, while completing DNA sequencing is a critical step in understanding genetic materials, it is more about providing foundational knowledge rather than a direct outcome of genetic engineering. Creating genetically identical animals, often associated with cloning, is a different process and isn't typically regarded as an objective of genetic engineering itself. Lastly, while genetic engineering can influence populations and conservation efforts, the extinction of wild species is generally not a direct outcome of genetic engineering; instead, it's more of a consequence seen in relationship to habitat changes and overexploitation. Thus, the emphasis on the creation of desirable traits captures the essence of what genetic engineering aims to achieve in animal genetics.
