This indicated that the over-representation of certain
haplotypes occurred at the onset of breed creation as a result of small founder numbers, and / or that it was associated with artificial genetic bottlenecks that were subsequently masked by a return to random selection.
Among breeds,
this haplotype occurs in 5 breeds and is most common among Shetland Sheepdogs, Border Collies, and Cairn Terriers.
Part of the A2b haplogroup,
this haplotype occurs most commonly in Labrador Retrievers, Rottweilers, Curly - Coated Retrievers, Dandie Dinmont Terriers, and village dogs throughout the world.

haplotype occurs as expected in several bracycephalic breeds that include «bull» in their breed names, as well as breeds such as the Beagle, Coton de Tulear, and Wire - haired fox terrier.

Here, for the first time, we specifically define cases of immediate adaptive introgression (iAI), in which archaic

occurred shortly after the introgression event.

occurred ~ 1,200 years ago.
As a consequence, the possibility has been raised that admixture did
occur, but the early Europeans of modern anatomy were not too different genetically from Neandertals, or else that most Neandertal
haplotypes were lost through a process of lineage sorting, i.e. by genetic drift [5].
