About what precentage of all existing transgenic animals are mice?

Options

A. 75
B. 95
C. 100
D. 50

Answer

To determine the percentage of all existing transgenic animals that are mice, we can follow these steps:

1. **Understanding Transgenic Animals**: Transgenic animals are those that have had their genomes altered through genetic engineering. Mice are one of the most commonly used transgenic animals in research.

2. **Research Context**: Mice are frequently used in genetic research due to several advantageous traits. These include their high reproductive rate, which allows for rapid generation of offspring, and their relatively simple care and monitoring in laboratory settings.

3. **Percentage Calculation**: According to research and data in the field of biotechnology, it has been established that approximately 95% of all existing transgenic animals are mice. This high percentage is attributed to the reasons mentioned above, including their ease of manipulation and monitoring.

4. **Conclusion**: Therefore, the answer to the question is that about 95% of all existing transgenic animals are mice.
