Inheritance and linkage of allozymes in seed tissue of whitebark pine
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.Key words: Pinus albicaulis, isozymes.
