This resource is already yielding several lessons: one, the number of stem cell lines needed to analyze polygenetic disease may not require hundreds of samples.
In sections on phylogeography and speciation, mating, evolutionary processes, and conservation, biologists look at such topics as the formation of landlocked populations of Atlantic salmon, the brain-pituitary-gonad axis in the Atlantic salmon, the effect of sperm competition on effective population size, the polygenetic analysis of the evolution of semelparity, and captive breeding and conservation.
For the polygenetic scoring analyses, in addition to all 2,053 HEALS samples with metabolite data, which constituted the training set, HEALS also contributed 1,285 controls and 24 skin lesion cases to the "testing" set.
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.
Richter and Yaalon (2012) discussed this conceptual 'mirror-to-memory transition' and concluded that most soils comprise both characteristics that developed under the present environmental conditions, and features that reflect different conditions that the soils experienced in earlier periods of their residence time; they are thus polygenetic, representing both mirrors and memories of landscapes.
DISCUSSION: Genodermatoses are inherited genetic skin conditions often grouped into three categories: chromosomal, single gene, and polygenetic.
Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a progressive neurodegenerative disorder associated with polygenetic, maternally inherited mutations in mtDNA.
Thus, when the author discusses the problem of "Ignoble Savages," as chapter 3 is titled, she is able to show how Karnes's argument was part of a larger European tradition that included Voltaire, Hume, and others who tried to explain the apparent permanence of the savage state in America by reference to polygenetic theories of separately created races, while Robertson's depiction of American Indians as indolent and defective due largely to their environment meshed with the views of Buffon and especially de Pauw.
The HLA DQ2 or DQ8, found in 30% to 40% of people, is necessary for the celiac disease autoimmune response, but recent genome-wide association studies have identified dozens of genetic risk loci, indicating that celiac disease is a complex, polygenetic immune-based disorder (Lebwohl et al.
The polygenetic relations between the 50 isolates were obtained by building a Neighbour-Joining (NJ) tree (Jin & Chakraborty 1993) using Populations 1.
It was pointed out earlier that Eurasians qualify as mutations in the biogenetic sense as the monogenetic thesis of human origins has triumphed over the polygenetic, Diop, 1978, 1991; Wobogo, 1976.
