Segregation of polymorphic diallelic loci, which encode isozyme synthesis in seed endosperms of Pinus Sylvestris L. trees exposed to various levels of radiation after Chernobyl' meltdown, was studied. It was shown that directional gametic selection, expressed as segregation distortion in heterozygotes, is observed in irradiated populations for a number of loci. The detected selection has one-locus character and distinctly influences the gene pool of the next generation.
