If you have one as a result of breeding it’s up to you what you do but they will not typically live as long as healthy mice and will have other abnormalities.

Mouse Breeding and Genotyping

Genotyping results in different genes and mouse abnormalities. Genotyping is the process of examining DNA and separating genes and using them to change the genetic make-up of an animal.

Genotyping is an important part of scientific research and is responsible or finding cures to diseases and changing bacteria’s, Regardless of our own personal thoughts about the use of laboratory mice. These processes have helped medical and scientific advancements.

Mouse Breeding Colony Management

Laboratory mice provide an important role in bio-medical research and development. Gene-targeting and manipulation of gene strains is done to modify the DNA make up of mice for study and research purposes.

This results is all kinds of abnormalities and different looking mice. The GREM1 gene is responsible for the abnormality resulting in the lop-sided ears that make the gremlin mouse.
