The dog is black all over the body, the hairs are not bicoloured (brown/black) as in the other agouti genes. This colouration is caused by the recessive a allele of the Agouti locus.

Runs of Homozygosity (ROH) are contiguous stretches of homozygous genotypes that can be found in an individual's genome. They arise from the inheritance of identical segments of DNA from both parents, often due to mating between relatives. Analyzing ROH can provide valuable insights into genetic diversity, inbreeding levels, and overall health of populations.

ROH profiles, along with the genomic inbreeding coefficient (GIC) and heterozygosity values (HE) , are modules of genome-based evaluation for inbreeding & fitness and for mating planning based on this, taking genetic diversity/inbreeding into account.
