Analysis of complex allozyme polymorphisms in a barley population.
Genotypes of 68,230 individuals taken from 10 generations (F(4)-F(6), F(14)-F(17), F(24)-F(26)) of an experimental population of barley were determined for four esterase loci. The results show that frequencies of gametic ditypes changed significantly over generations and that striking gametic phase disequilibrium developed within a few generations for each of the six pairwise combinations of loci which were monitored. The complex behavior of these four enzyme loci in the population is attributed to interactions between selection and restriction of recombination resulting from the effects of linkage and/or inbreeding.
