And this experiment is helpful because....?

Because if you can transplant genes, it would become possible to share advantageous features of genetics across the species barrier. It could be immunity to certain diseases, diabetes, heart disease, or eugenics, etc.

In part, because it gives a way to “tag” a gene to make it visible without harming the animal. The research potential of the technique is limited only by the researchers’ imaginations. So much of animal research depends on having to sacrifice the animal at some point during the experiment; a technique like this makes it possible to make the observations without sacrificing the animal. Plus, observations of a couple animals over time are far more valuable than observations of several animals at a single time point.

I could go on and on about this, so I will stop now and spare everyone the wall of text.
