Linkage between the X-linked green tail gene (Grt) and blue tail gene (Blt) determining tail color in the Green Snakeskin and Blue Snakeskin varieties of the guppy (Poecilia reticulata), respectively, was determined from segregation data of F2 progeny from single-pair reciprocal crosses between these two varieties. The Grt and Blt genes are both dominant and X-linked but they are non-allelic. The average map distance between them was found to be 19.4 map units.
