That is a very tough not question to answer, because correctional facilities ALWAYS mirror their real world counterpart for their respective regions. This is to say, while both in American prisons and Brazilian ones the female counterparts of gangs in male prisons, their goals are entirely different. Where racial wars go on in American prisons, below the surface they're still businesspeople so the coordination of sale of drugs and weapons goes on between them (for example the ATF has in coordination with the DEA reported that white nationalist gangs unable to legally buy weapons sell crystal meth to black street gangs for their under the counter weapons), in Brazil, the paramilitary groups running favelas are underlings of prison gangs who carry out turf wars within confinement.
That's about the criminal side of the situation. From law enforcement, wherever judges and district attorneys run for reelection, heavily sponsored by the private prison industry, corruption is not unheard-of. Some of these facilities ran pretty much on Dickensian conditions. It's pretty much a given globally that the fewer resources are known to be available, humans behave more animalistic to survive. It doesn't lead to sexy shower or mud puddle fights.
Finally, there are some classical, and some relatively new targets, like trans people. The classic ones are a bit different for male and female prisons where men despise pedophiles and rapists the most, for women it's the child murderers.
What we get to see in exploitation isn't real, which would be fine if the fiction would be a bit based in reality, but isn't. The upside of that is that prisons have a double strict control. Not many would want to see The Godfather as played by John Gotti where the action takes forever because it has to be kicked up the chain. Women obviously don't act so differently from us when they're the majority which means a strict pecking order.
