Demographic assessment of the Dalmatian dog - effective population size, linkage disequilibrium and inbreeding coefficients.

ABSTRACT:

Background

The calculation of demographic measures is a useful tool for evaluating the genomic architecture of dog breeds and enables ranking dog breeds in terms of genetic diversity. To achieve this for the German Dalmatian dog population, 307 purebred animals of this breed were genotyped on the Illumina Canine high density BeadChip. The analysis of pedigree-based inbreeding was performed based on a pedigree with 25,761 dogs including the genotyped dogs.

Results

The effective population size derived from squared correlation coefficients between SNP alleles (r ²) was 69. The maximum value of r ² was 0.56, resulting in a 50% decay value of 0.28 at a marker distance of 37.5 kb. The effective population size calculated from pedigree data usin
