Transgenic Mice. One of the simplest ways to study gene function in a mouse is exogenous expression of a protein in some or all tissues. For this type of genetic modification, a new piece of DNA is introduced into the mouse genome.ne of the simplest ways to study gene function in a mouse is exogenous expression of a protein in some or all tissues.

Using knock-in genetic engineering, Jacobs et al. have effectively created a mouse with a retina like that of a New World monkey, with one very important difference: mice do not have well-developed form vision, and do not have midget cells. Mice do not already have the hardware that many assume is a critical first step to the evolution of color vision. Despite this, three of the five transgenic heterozygote female mice tested by the authors could discriminate reds from greens, showing color matches remarkably similar to humans .
