More than 95% of transgenic animals are

Options

A. Rabbits
B. Mice
C. Fish
D. Cows

Answer

**Step-by-Step Solution:**

1. **Understanding Transgenic Animals**:
- Transgenic animals are defined as those that have had a foreign gene deliberately inserted into their genome. This process allows researchers to study the effects of specific genes and their functions.

2. **Recombinant DNA Technology**:
- The foreign gene inserted into the transgenic animal is constructed using recombinant DNA technology. This method involves combining DNA from different sources to create a new genetic sequence.

3. **Research Foundation**:
- The Foundation for Biomedical Research (FBR) conducts studies on transgenic organisms. Their research provides insights into the prevalence and types of transgenic animals used in scientific studies.

4. **Statistics on Transgenic Animals**:
- According to the FBR, it has been found that more than 95% of all transgenic animals are either mice or rats. This statistic highlights the dominance of these species in transgenic research.

5. **Conclusion**:
- Based on the information provided, the final answer to the question "More than 95% of transgenic animals are" is that they are primarily mice.

**Final Answer**: More than 95% of transgenic animals are mice.
