Allozyme variants were examined for 12 enzyme systems in haploid megagametophyte tissue of whitebark pine (Pinus albicaulis Engelm.). Inheritance and linkage information is reported for 11 loci (Aat-3, Aco, Adh, Fle-2, Idh, Mdh-2, Mdh-3, Mdh-4, Mdr, Pgi-2, and Pgm-2). Deviations from a 1:1 segregation ratio were observed at Fle-2, Pgi-2, and between two of the three alleles at Mdh-4. Significant linkage was observed for two pairs of loci (Aco–Fle-2 and Adh–Pgi-2), but estimates of recombination frequencies were relatively high.
