A more relevant and important question for them would be if they are the same blood types or not, I'd think. I suppose potential organ transplants are the most justifiable reason for them to actually bother finding out for sure.

I believe this could turn into a fascinating storyline and would lead readers to question their conception of family.

It is in the core of TMNT that family goes beyond blood ties, so keeping on exploring this thematic that way would have a great potential.

Imagine the turtles find out that 3 of them are actually blood brothers while the 4th one is not. How would they react?
In my opinion, that is a very interesting starting point that deserves to be developped.
