" If you cross two Greenish Rats, do they breed true? Are 100% of the offspring greenish in coloring?"

Well, I think this would depend on where the two parents came from in their natural overlap range. Some would naturally vary from individual to individual just like any type of snake would in their natural range, but I seriously doubt any would ever look like either textbook Black or Yellow parent like if you tossed two textbook examples of Black and Yellow Rats together in a captive-produced project in an F-1 generation and so on. If some were bred from the very fringes of an intergrade zone where you tended to find Yellows, Blacks, and intermediate phenotypes it could be very different story though.

The animals in Jim's immediate area seem to prove this as well along with what he has produced. My locality-specific normal het "moonshine" pair I got from him vary slightly, but both still look like perfect intergrade "greenish" phenotypes through and through.One is a tad grayer, and the other is a bit greener, but both are still very green with the typical patterning of both subspecies they are derived from.
