Origin of the domestic dog matched across Eurasia and its branch is phylogenetically rooted in the same sequence as the Altai dog (not a direct ancestor). The subclade d2 hybrid haplotypes are found in 2.6% of South-West Asian dogs. Haplogroup E: Derived from post-domestication wolf–dog hybridization in East Asia, (rare distribution in South-East Asia, Korea and Japan). Haplogroup F: Derived from post-domestication wolf–dog hybridization in Japan. A study of 600 dog specimens found only one dog whose sequence indicated hybridization with the extinct Japanese wolf. It is not known whether this hybridization was the result of humans selecting for phenotypic traits from local wolf populations
Ticks of domestic animals as an adult on another cow in a three-host lifecycle. Furthermore, this tick commonly feeds as a three-host tick with larvae, nymphs, and adults feeding on separate individual dairy cows confined to cattle housing in zero-grazing systems. "Argas persicus", the fowl tick, is a major pest of poultry birds (see Gallery below for photograph). The tampan ticks within "Ornithodoros moubata" complex of species infest domestic pigs and also feed on humans. "Ornithodoros savignyi" is often found in large numbers at enclosures where camels and cattle are herded. Many species of argasid soft ticks are adapted to live in the nest
