Finally, to assess whether genetic differentiation follows a pattern of isolation by geographical distance (IBD), the Euclidean geographical distances between populations were obtained through the program ArcGis v.
We did not detect significant genetic differentiation related to host species when analyzing data from 11 nuclear microsatellite loci and mitochondrial sequence data, which is comparable to findings for the Pacific lineage.
In order to observe the genetic differentiation in lower Khyber Pakhtunkhwa (KPK) region, ABO and Rh blood groups record of nine Pashtun populations, i.
On contrary, the overall sample of mahseer population exhibited higher values of genetic differentiation (Rst; 0.
However, these analyses included only a small sample from one AP site (Taylor and Hoffman, 2012); also, Peromyscus species typically display lower levels of genetic differentiation than most mammals (e.
Until now no genetic analyses have been done to determine if the degree of genetic differentiation of Harvey Lake from other Isle Royale populations might support Hubbs and Lagler's subspecies hypothesis largely due to the inaccessibility of the island lakes and the difficult logistics of ichtyofaunal survey on Isle Royale.
These data indicate that the collected populations were essentially panmictic, and there was little genetic differentiation among them, further suggesting that there was high gene flow among the populations.
