The average marker interval was 17.6 cM (sex-averaged map distance).
The sex-averaged linkage map spanned a total of 3057 cM with an average marker spacing of 2.1 cM.
We found the average marker retention frequency to be 18.4%.
The animals were genotyped for 5 microsatellite markers each on regions of BTA 4 (average marker spacing 9.42 cM) and BTA 26 (average marker spacing 5.26 cM), previously reported by other authors as carrying QTL for somatic cell count.
The average marker interval was maximum in C3 (8.23 cM) while it was lowest in C10 (5.78 cM).
This map is fairly saturated with a total length of 1226 cM and an average marker spacing of 3.75 cM.
The average marker density was 5.6 SNP markers per cM or 3.3 SNP markers per recombination point.
Then, 6601 evenly distributed SNPs with average marker spacing around 50 kb were sampled to calculate population structure (Q).
Average marker spacing was 66.5 kb.
The average marker heterozygosity was 0.777 (range 0.462 0.941).
The overall map length is 745 cM, with an average marker distance of 1.98 cM.
