The Sulimov dog originated in Russia from an initial hybrid between Nenets Herding Laika and golden jackals to produce one-quarter jackal hybrids. The hybrid was developed by Klim Sulimov. [a] [11] The resulting breed was thought to have the jackal's
[32] [33] Hybridization also occurs between female golden jackals and male dogs, which produces fertile offspring, [34] a jackal–dog hybrid. There was 11–13% of ancient gene flow into the golden jackal from the population that was ancestral to wolves and dogs, and an additional 3% from extant wolf populations.
The discovery of these specimens confirmed that hybridization between the two canids occurs in the wild, and that the two have unlimited fertility with each other. [27] Although hybridization between wolves and golden jackals has never been observed, evidence of such occurrences was discovered through mtDNA analysis on jackals in Bulgaria. [28]
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
This result suggests a common origin for dominant yellow in dogs and white in wolves but without recent gene flow, because this light colour clade was found to be basal to the golden jackal and genetically distinct from all other canids. The most recent common ancestor of the golden jackal and the wolf lineage dates back to 2 million YBP.

As jackal hairs have very little fur fiber, their skins have a flat appearance. The softest furs come from Elburz in northern Iran. [27] Jackals are known to have been hunted for their fur in the 19th century: in the 1880s, 200 jackals were captured annually in Mervsk. In the Zakatal area of the Trans-Caucasus, 300 jackals were captured in 1896.
The Egyptian wolf had an unresolved taxonomic identity and was formerly known as the Egyptian jackal. Throughout much of the 20th century, the animal was classed as a subspecies of golden jackal, Canis aureus lupaster. Notice was however taken by numerous zoologists of the animal's morphology, which corresponds more to that of the grey wolf.
