Along these lines, we found a modest and marginally significant positive association between chromosome size and mean log cline slope or gradient ( v ) when considering the subset of chromosomes with at least five ancestry informative SNPs (linear regression, df = 17, β = 2.6 , s.e. = 1.4 , r 2 = 0.18, model p = 0.017).
