From: Estimates of linkage disequilibrium and effective population size in rainbow trout
Decline of linkage disequilibrium ( r2) with distance (recombination rate in Morgans) for chromosomes 13, 14, 17 and Sex. The estimates of r2 for pairs of markers were adjusted for experimental sample size 1/n, were n is the chromosome sample size (n = 192). The predicted LD value plot (filled non-linear curve) was estimated fitting the equation LD ij = 1/(1+kb j d ij )+e ij performing non-linear modeling with JMP® Genomics 3.1 (SAS Institute Inc., Carey, NC, 2007). Here, LD ij is the observed LD for marker pair i in chromosome j, d ij is the distance in Morgans for marker pair i in chromosome j, b j is the estimate of effective population size for chromosome j, and the constant k = 2 for sex chromosome and k = 4 for autosomes.
