Table A1. Number of Single Nucleotide Polymorphism (SNP) markers (m) and chromosome length (mega base pairs, Mb) for 29 bovine autosomes (BTA 1 to BTA 29) in the Kinsella composite beef population. Mean, standard deviation (SD), minimum and maximum distances (in base pairs) between all pairs of adjacent markers are also presented. Table A2. The proportion of syntenic SNP pairs with out-of-bound estimates of generalized measures of squared correlation for trigenic and quadrigenic disequilibria in the Kinsella composite population. Table A3. Summary statistics on single-locus heterozygosity, fixation index and Hardy-Weinberg disequilibrium (HWD) averaged over all SNP markers on 29 bovine autosomes (BTA 1 to BTA 29) in the Kinsella composite beef population. Appendix: Sampling variances of individual genic disequilibria in zygotic LD.
