If the Project takes the other direction, then the discovery of polygenetic interaction, the tremendous complexity of what we had expected and hoped to pare down to cultural "size," will require that we rethink our biopsychosocial world view.
Primary osteoporosis is a polygenetic disease characterized by an imbalance of bone homeostasis including microarchitectural deteriorations and low bone mineral density [1].
The main target for the CGS study in Estonia, Latvia and Lithuania is the Baltic Basin (700 km x 500 km synclinal structure), a Late Ediacaran-Phanerozoic polygenetic sedimentary basin that developed in a pericratonic setting in the western part of the East European Platform.
DISCUSSION: Genodermatoses are inherited genetic skin conditions often grouped into three categories: chromosomal, single gene, and polygenetic. One such example for Genodermatoses is Palmoplantar keratodermas which are a heterogeneous group of disorders characterized by abnormal thickening of the palms and soles.
The presence of polygenetic soils may also introduce further weaknesses into the models and derivative maps.
Since obesity is a major environmental factor predisposing humans to T2D [20], it becomes necessary for a translational animal model to become obese by a polygenetic mechanism.
The polygenetic relations between the 15 isolates were obtained by building a Neighbour-Joining (NJ) tree (Jin & Chakraborty 1993) using Populations 1.2.28 Software (Librado & Rozas 2009).
For Morton as with Arthur de Gobineau and others, none of the accomplishments of ancient Nile Valley Egyptian civilization could be attributed to Negroes (Africans), for that would clearly grant intellectual power and capacities to enslaved Africans' ancestors unaccounted for in the inferior race pronouncements of the polygenetic theorists.
Polygenetic analysis of 16SrDNA strongly suggested that the bacterial isolates 3B, SI, 2A and 3A may be members of the genus Pseudomonas on the basis of their closest relatedness.
The reasons why this topic remains debatable and debated are more logical than technological: I draw attention to the fact that all the models designed and tested until now--whether stemmatic or non-stemmatic --have given taxonomic results, that is, they prove that the documentary incompleteness of tradition, contamination, interpolation, and polygenetic phenomena are all factors which, even when resorting to mathematical calculations, do not yield exact solutions, but only approximate results.
However, the observed high variability in the trace metal composition of GA, including heterogeneous REE patterns, points to the polygenetic nature of metal assemblages, apparently formed as the cumulative product of multistage evolution.
In terms of engineering geology, according to engineering-geological zoning maps [18, 20-22], in the study area there is a zone of polygenetic loess sediments which is the largest and takes up 45.9% (556.1 [km.sup.2]) out of the total study area of 1197.4 [km.sup.2].
