542), indicating that gene frequencies of this locus had reached genetic equilibrium and it was group-representative.
Also demonstrated was a disturbance of genetic equilibrium estimated according to the Hardy-Weinberg formula.
On islands closer to the mainland and smaller in size, in contrast, genetic equilibrium will attain sooner, without any signs of phenotypic changes (Kneiss Island).
In milk-producing cattle when milk protein genes are in genetic equilibrium it is an indicator of the absence of selection processes (Gouda et al.
7246 for this study), are derived on the basis of simplified models of population structure that assume constant population sizes, symmetrical migration at constant rates, and population persistence for periods long enough for achievement of genetic equilibrium (Wright, 1969).
Specifically, is there evidence for "mating trials" between what have become full siblings, and, if so, are the various combinations of sex chromosome types in genetic equilibrium suggesting an incipient speciation event?
to encourage development of national policies to ensure sustainable utilisation and conservation of tropical forests and to protect genetic equilibrium in the relevant regions.
Neutral theory predicts that populations should be in genetic equilibrium (and that complete lineage sorting should have occurred) if time since divergence (t) exceeds 4[N.
While classical isolation-by-distance models suggest that gene flow between these populations is low enough to allow divergence under conditions of genetic equilibrium, there has not been enough time since the last sea-level rise for a homogeneous stock to have differentiated without strong selection.
The gene distribution of GUJ0077 presented significant deviations from the genetic equilibrium (P(less than)0.
gallicus is in genetic equilibrium, the majority of populations studied are at least moderately linked by seed flow.
