Nonetheless, populations within the presumptive hybrid region exhibit significant gametic disequilibria
and high fixation indices, likely because of assortative mating and/or differential fitnesses of species- specific versus recombinant genotypes.
First, it is demonstrated that the statistical power estimated assuming that the sample disequilibria
reflect the true population values, is remarkably low.
A computer program for testing pairwise linkage disequilibria
in subdivided populations.
We can thus see that the doctrinal standoff between Portes and Kornai did not prevent a burgeoning of the literature examining disequilibria
and shortages in CPEs.
On the other hand, looking at the anomalies in the structure of prices and remuneration rates is as important as looking at excess demands and supplies, because these anomalies play an important role in market disequilibria
. They have often been called "distortions"; but using this word may convey the idea of a deliberate action at imposing wrong prices.
The full distribution of genotype frequencies is described by higher-order linkage disequilibria
(e.g., involving the correlation between heterozygosities at different loci; Weir and Cockerham 1989).
The issue in this study is one of political economy, concerning the adjustments of expenditures and revenues to budgetary disequilibria
. Questions of effects of fiscal policies or of sustainability of deficits are not the concern of the present paper, and the related issues of variable definitions do not apply here.
were ignored, following Barton and Gale (1993).
among pairs of loci could be tested for 130 combinations over the 13 samples (Table 1).
In previous analyses of cytonuclear disequilibria
in hybrid zones it has been assumed that codominance holds between alleles at nuclear loci in the cytonuclear system (Asmussen et al.
Consequenctly, linkage disequilibria
are reinforced, and the effective selection per locus remains high.
and [Delta][p.sub.i] and [Delta][D.sub.ij] are differences between the gene frequencies and the linkage disequilibria
in the hybrid group H and population R:
