Sentence examples for genetic boundaries from inspiring English sources

Current data refute the notion that 'races' and 'ethnicities' are genetically distinct human populations as no sharp genetic boundaries can be drawn between human population groups [ 10].

"Language has a role in forming genetic boundaries, too.

We have stressed the fact that the identification of genetic boundaries is highly dependent upon the sample set available for the analyses; that is, significant genetic barriers are susceptible to be detected through uneven sampling along genetic clines!

Descriptive approaches like PCA, MDS, spatial autocorrelation analyses aiming at detecting genetic clines, specific statistical analyses used to identify genetic boundaries, as well as correlation analyses allowing the comparison of genetic variation with either geographic or linguistic data are still very useful to understand how the current genetic pool of East Asian populations is structured.

The Samova analysis [40] allows to determine genetic boundaries between n populations by using both their geographic location and their allelic frequencies at a given locus.

In addition, the pattern of genetic differentiation revealed a contrast in population structure at different spatial scales: (1) weak spatial structure at a regional scale (on the order of 100 s of kms) and (2) distinct genetic boundaries within a 2 km shore.

Population genetics results identified two subpopulations and delineated a genetic boundary between the Dzungarian and Transaltai Gobi for which the most likely explanation are the mountain ranges separating the two areas.

The genetic boundary of P. henryi and P. tabuliformis generally coincides with the previous morphological dividing line based on the unweighted pair group method using arithmetic averages and on spatial analysis of molecular variance.

Han populations are less diversified (lower F ST) than Tibeto-Burman but a significant genetic boundary is found between northern (mostly Mandarin-speakers) and southern (mostly speakers of Southern languages) Han populations (Di and Sanchez-Mazas 2011; Poloni et al. 2005), although Mandarin populations from Southwest China show smaller genetic distances to SEAS than to NEAS.

Note that the significant level of genetic variation (Φct = 0.16) observed by Karafet et al. (2001) between SEAS and NEAS for the Y chromosome cannot be interpreted as a genetic boundary as it is the result of an analysis of molecular variance (AMOVA) with an a priori choice of the groups compared.

The existence of a clear-cut genetic boundary between northern and southern populations has been debated: based on classical markers, a boundary located at the vicinity of the Yangtze River has been suggested (Du et al. 1997; Xiao et al. 2000; Xue et al. 2005).
