That implies the ADH1B haplotype pattern in SN may be due to selection, and the selective forces on ADH1B may be something like ethnic culture.
Since the specification tests imply that even such modest earnings benefits could be due to selection, our results with this selected group confirm our findings that the WIA Dislocated Worker program has little impact on participants' earnings.
This result could be due to selection if women workers from low female labor supply countries are positively selected relative to women workers from high female labor supply countries.
The evolutionary reversal of a CA bias to a GT bias found in some lineages of chelicerates may be due to selection, rather than to neutral processes, although it is not clear what the selective force may be.
In the senior author's view, this is a rather interesting and unusual finding, and may be due to selection bias.
This discrepancy may be due to selection of a different set of manually curated atom mappings from the KEGG RPAIR database [2].
Some of this pattern appears to be due to selection into higher paying jobs rather than positive discrimination in favour of white immigrants (Elliott and Lindley 2008).
If the association observed in the OLS estimates disappears in the fixed effects results, this is an indication that the association may be due to selection.
Since the data collection and headache classification was completely standardized with trained interviewers across all studies, this is unlikely to be due to selection or recall bias.
Thus, SCU bias might be due to selection of codon usage for optimal gene expression.
In contrast, non-linear increases in mutation probability with male age might be due to selection for mutations in the germline prior to meiosis [35], [36].
