Why fracture location seems to differ between different populations is not clear.
For visualizing the AMOVA results, multi-dimensional scaling plots based on pairwise Fst-values were generated with PASW Statistics 18 (SPSS Inc .. Differences in haplogroup-distributions between different populations were evaluated with a Chi-Square Test.
Differences of susceptibility to pathogen infection between different populations were previously observed in other bivalves [ 11, 12].
Fluctuations in size and appearance between different populations are outweighed by variations within the populations themselves.
As a matter of fact, the knowledge of genetic distances between different populations is helpful in defining which biobanks could sensibly contribute samples and data to GWAS.
The genetic distances between different populations were calculated as previously described by Nei [65] and a phylogenetic tree was constructed based on the allelic frequencies of HLA-B locus with the Mega 3.1 Software package (Center for Evolutionary Functional Genomics, the Biodesign Institute Tempe, AZ, USA) using the Neighbor-joining method [66].
The comparability of this measure between different populations is reasonably good, if it can be assumed that the severity of occupational asthma is similar in different populations.
For example, in D. mojavensis, variations in CHC blends between different populations are thought to be caused by feeding on different host plants [ 52, 53].
However, the reason for the substantial variation in the secular pattern in the age-adjusted incidence between different populations is unclear.
Most probably, dispersal between different populations is a relatively rare event taking place as passive aerial dispersal of very small larvae [ 31].
