While it's human nature to gravitate toward some people over others, the problem arises when there's a perception of exclusivity and favoritism surrounding a select few.
The integrated haplotype score (iHS) is based on the differential levels of linkage disequilibrium surrounding a positively selected allele compared to the background allele at the same position (Table S1) [5].
iHS is a statistic that was developed to detect evidence of recent positive selection (<30,000 years ago) at a locus, and is based on the differential levels of linkage disequilibrium surrounding a positively selected allele compared to the background allele at the same position.
This measure has been developed to detect evidence of recent positive selection at a locus and considers differential levels of linkage disequilibrium (LD) surrounding a putatively selected allele by comparing it to LD around the alternative allele at the same position [13].
Each night one moth was released into each of the 12 netting 'sleeves' surrounding a branch selected randomly from among the 103 (reduced to 97 by 2007) branches used in the study.
where p and q, respectively, denote the positions of the central and surrounding pixels in a selected window N(p), while I(p) and I q) represent their corresponding intensities of the pixels.
Sites under strong positive selection work in pairs, 2 positively selected codons surrounding a site under strong purifying selection (codons 8 and 26).
