A Fiat shares a lot of physical characteristics with a Lamborgini.
You don't care, I say that there is some difference.
Humans share lots of genes with the mouse. We share ~99% of the genes.
However, religious and ethical believes of many people might tell
them that is not the same to eat rat, pig, human or chicken.

Religious and cultural differences aside, I think having rats
with a complete set of the human immune system running
around in the sewer systems of the world is not a good idea
either. Each organism has it's niche and broadening might not be
a good idea. It might expose us to unknown pathogens.

would you care if grampa's genes where in your pigs?

No. Why should I?
I wouldn't care if some of my genes were in a pig.
We share lots of genes with pigs anyway.

latest figures was we are 300 genes different from mice, which isn't a
lot in 30,000+ genes.
