摘要：

The associations of alleles at different electrophoretic loci observed in barley and wild oats can be explained by hitch-hiking due to the mating system. In other words, selection at other loci in the genome may have resulted in gametic disequilibrium or a change in gametic disequilibrium at neutral loci in these highly self-fertilised plants. This explanation appears to be a simple alternative hypothesis to account for the change in gametic disequilibrium in barley and the presence of gametic disequilibrium in wild oats. However, it appears difficult to differentiate experimentally between the hitch hiking and the previously proposed coadaptation hypotheses. © 1979 The Genetical Society of Great Britain.
