Origin of the domestic dog to the domestic dog and modern wolf lineages. The gray wolf is thought to be ancestral to the domestic dog, however its relationship to "C. variabilis", and the genetic contribution of "C. variabilis" to the dog, is the subject of debate. The Zhokhov Island (8,700 YBP) and Aachim (1,700 YBP) canid haplotypes fell within the domestic dog clade, cluster with S805, and also share their haplotypes with – or are one mutation away from – the Tibetan wolf ("C. l. chanco") and the recently-extinct Japanese wolf ("C. l. hodophilax"). This may indicate that these canids retained the genetic signature of
Mites of domestic animals reaction in the host, but pruritus, seborrhea and pustules in the skin may develop as an allergic reaction to the mites. The adult mites are visible crawling in the fur and may cause similar skin reactions in the pet's owner. Other genera of mites that cause similar problems in colonies of rodents are "Myobia" and "Myocoptes". The genus "Megninia" has species found on the feathers of poultry birds. Compared to ticks and insects of domestic animals the parasitic mites are of limited importance as transmitters (vectors) of pathogenic organisms to domestic animals. Some mites are the intermediate host of parasitic
