Summary Genetic linkage between the equine loci for phosphohexose isomerase (PHI) and serum Xk protein was demonstrated by means of segregation data from three sire families. The recombination frequency was estimated from pooled data to be 0.23 ± 0.02; a significant heterogeneity between sires for estimates of the recombination frequency was observed. No indication of linkage was detected between Xk and 14 other blood marker loci. Linkage between the Xk locus and the locus for soluble malic enzyme ( ME1 ) has recently been reported in horses. An equine linkage group designated LG IV comprising the three loci ME1, PH1 , and Xk has thus been established. The possibility that the linkage between PH1 and Xk is homologous to the linkage between the loci for PHI and a serum postalbumin (PO‐2) in pigs was discussed.
