Which of the following is not produced as transgenic animals

Options

A. Sheep and pig
B. Rat and Rabbit
C. Dog and Banded Krait
D. Cow and Fish

Answer

To determine which of the following is not produced as a transgenic animal, we need to first understand what transgenic animals are and then evaluate the given options.

### Step-by-step Solution:

1. **Define Transgenic Animals**: Transgenic animals are those that have had a foreign gene deliberately inserted into their genome. This is typically done using techniques such as microinjection of DNA into embryonic stem cells.

2. **Identify Common Transgenic Animals**: Some of the most common transgenic animals include:
- **Rats**: Often used in research due to their short reproductive cycles.
- **Pigs**: Used for organ transplantation.
- **Sheep**: The first cloned sheep, Dolly, was created to enhance wool quality.
- **Rabbits**: Used to produce recombinant proteins, such as the human C12 asterase inhibitor.
- **Cows and Goats**: Engineered to produce more milk or meat and improve disease resistance.

3. **Evaluate the Options**: The question provides several options, and we need to determine which one is not a transgenic animal. Based on the information provided:
- **Rats, Pigs, Sheep, Rabbits, Cows, and Goats** are all examples of transgenic animals.
- **Dogs** and **Bended Crates** (assuming this refers to a specific breed or type that is not commonly recognized in biotechnology) are not typically used as transgenic animals.

4. **Conclusion**: After evaluating the common examples of transgenic animals, we can conclude that the animal that is not produced as a transgenic animal is likely the **Dog** or **Bended Crates**.

### Final Answer:
The correct answer is **Dog** (or Bended Crates if that is indeed a specific breed).
