i know that the redxblue crosses at st. pierre's produced babys, so they are fertile (at least a couple of them). what would happen if you tried breeding one with a pure red or blue tegu? do you think it would work? the redxblue cross would be closer related to a pure blue or red than the original pairing of red and blue did, and they produced fertile offspring. just thinking aloud. i have a year old red and am considering getting another tegu, and i'm fond of the way the redxblues look. tell me what you think.
