Question

Maximum number of existing transgenic animals is of

• A. Fish
• B. Mice
• C. Pig
• D. Cow

Answer 1

The correct option is B Mice

Transgenic animals
Transgenic animals are those that have one or more foreign genes from another species introduced into them by artificial means for the expression of desired traits.

Maximum number of transgenic animals
The protein-coding regions of mice and the human genome are about 85% identical due to which mice are used in genetic research, genetically modified as disease models to understand human diseases.

• They are cost-effective and easy to look after.
• They can reproduce as often as every three weeks.
• They are easy to handle which is why they are the choice of scientists for research.
• Thus, the maximum number of transgenic animals created are mice.

91.4 % of all experiments use genetically modified mice.

Final answer
c. Mice
