Table 1 Means and standard deviations (SD) of gametic LD ( φ GLD 2 a ), composite LD ( φ CLD 2 ) and zygotic LD ( φ ZLD 2 a ) between syntenic SNP pairs for different ranges of distance (≤ 5 Mb) in the Kinsella composite beef population

From: Genome-wide analysis of zygotic linkage disequilibrium and its components in crossbred cattle

  1. Percentages of SNP pairs with LD values of ≥0.25 are also presented. a The Generalized measures of gametic and zygotic LD ( φ GLD 2 and φ ZLD 2 ) are based on an exact 2 × 2 contingency table and thus they are simply the squared correlations, i.e., φ GLD 2 = r GLD 2 and φ ZLD 2 = r ZLD 2 .
