We have identified 8 SNP
sites at hsp70 gene,. Figure shows the allele frequencies at each of 8 SNPs
for hsp70 gene in different regions. SNP sites are represented by these
individual bars, Individual bars are colored to show the frequency of each
nucleotide base as you can see in the legend. I hope you can see the
differences among the regional samples by the pattern of colors in
histograms. Because these sample sizes are small , we have done a preliminary
analysis by Monte Carlo
Chi-square test which shows highly significant differences among the
regional samples

We have also carried out a
within gyre analysis. We pooled the samples to represent the 3 gyres. So the
allele frequencies of the pooled gyre samples also indicated significant
population genetic heterogeneity among gyres (p = 0.0000 + 0.000)

|
An interesting result with
this gene is that the western NA populations came out to be very similar.
There were no differentiation among the samples.
|
|
On the other hand, there
were significant differentiation with the eastern NA and the Northern NA
gyres.
|
|
Nearly all variation is
neutral – differences NOT due to functional differences between genes
