Majority of transgenic animals are :

Options

A. Mice
B. Rabbit
C. Pigs
D. Cows

Answer

To solve the question regarding which animals are the majority of transgenic animals, we will follow these steps:

### Step 1: Understand the Definition of Transgenic Animals
Transgenic animals are organisms that have had a foreign gene deliberately inserted into their genome. This is done through biotechnology techniques, allowing them to express new traits.

**Hint:** Remember that transgenic animals contain foreign DNA that has been introduced for specific purposes.

### Step 2: Identify the Purpose of Creating Transgenic Animals
Transgenic animals are produced for various reasons, including:
- Improving the quality of livestock (e.g., better meat or milk).
- Increasing milk yield in dairy animals.
- Producing organs for transplantation.
- Research purposes, including studying diseases and genetics.

**Hint:** Think about the benefits that transgenic animals provide to agriculture and medicine.

### Step 3: List Common Examples of Transgenic Animals
Common examples of transgenic animals include:
- Mice
- Rabbits
- Pigs
- Cows
- Sheep
- Rats

**Hint:** Familiarize yourself with the common animals used in transgenic research.

### Step 4: Determine Which Animal is the Majority
Among the listed examples, mice are the most commonly used transgenic animals. The reasons include:
- Mice have a short reproduction cycle, allowing for quicker generation times.
- They are small and easy to handle in laboratory settings.
- They have a well-mapped genome, making them ideal for genetic studies.

**Hint:** Consider the practical advantages of using certain animals in research.

### Step 5: Conclude the Answer
Based on the information gathered, the majority of transgenic animals are mice.

**Final Answer:** The majority of transgenic animals are mice.
