2006 W. Sherwin & J. A. M. Graves in P. J. Armati et al. Marsupials ii. 44 It doesn't even have to be a coding region at all: any old piece of spacer, intron or pseudogene sequence can be located if a probe detects variation between different versions of the same DNA sequence in the two parent species.
