The reproduction level of rats is very high.Their reproductive rate is very high compared to others. They live a short life and can easily experiment on many generations of them within a short time.

3rd point:Close to the number of human genes

There is a lot of similarities between human and rats. Their genes are about 85% similar to us.Thats why on various experiment rats are used are the representatives of humans. New inventions like medicines are firstly experimented on them before using them on human. "Rats and mice are those creatures that has many similarities with humans and are suitable to use for the results in many researches " said by Jenny Haliski.

4th point:Genetically modifications

Another great reasons is their genetically modifications. Their genes can easily be modified and examine the results very easily. How different types of genes reacts on various experiments is usually the common reasons of using them. Scientists genetically-modified,which are called 'Transgenic rats". Selected genes can be turned on or made inactive which are called "knockout rats" these are generally used for our various disease purpose.
