To avoid these potential artifacts, we used the ratio of the sum of i discriminating haplogroup frequencies in the hybrid (ph) and source (ps) populations to estimate the admixture proportions relative to the closest outgroup population to the hybrid (p0): m=∑i(phi-p0i)∑i(psi-p0i).The...
we calculated a fold change ratio for every array position based on its normalized average intensity in each treatment (i.e., JH, SHE, LS, LR) divided by its normalized average intensity in the control
[70]. After normalization we determined a log2ratio (Queen's sample intensity/Worker's sample intensity), for each probe on each array. The fold-change in expression and its standard error for each gene were calculated by fitting a linear regression to the normalized expression data. A ...
In order to compare the anti-oxidant ability of apoLp-III and apoA-I in the lipid-free and lipid-bound state, both proteins were purified and synthesized individually as a palmitoyloleoyl phosphatidylcholine (POPC)-reconstituted high-density lipoprotein (rHDL) using the same molar ratio. In the...
Interior workers were also heavier and showed a higher gaster-to-head ratio and thorax ratio compared to exterior workers. An obvious difference between exterior and interior workers is activity level, but we found no link between activity and cold tolerance. This suggests that physiology rather ...
(A), soldier head extract(B), live reproductives(C)and live soldiers(D). The fold ratios on the x-axis represent the ratio of EST abundance for each of the four treatments relative to untreated controls. The numbers of contigs formed from ESTs of host or symbiont origin are given in ...
