Urban environments often favor coyote genes, while the ones in the rural and deep forest areas maintain higher levels of wolf content. A 2016 meta-analysis of 25 genetics studies from 1995 to 2013 found that the northeastern coywolf is 60% western coyote, 30% eastern wolf, and 10% domestic dog.
The eastern wolf probably was a result of a wolf-coyote admixture, combined with extensive backcrossing with parent gray wolf populations. The red wolf may have originated during a time of declining wolf populations in the Southeastern Woodlands, forcing a wolf-coyote hybridization, as well as backcrossing with local parent coyote populations ...
This canine has been named Canis latrans var. [3] and has been referred to as the eastern coyote, northeastern coyote, coywolf, [4] and the southern tweed wolf. [5] [6] Coyotes and wolves first hybridized in the Great Lakes region, followed by a hybrid coyote expansion that created the largest mammalian hybrid zone known. [7]
The red wolf is an enigmatic taxon, of which there are two proposals over its origin. One is that the red wolf is a distinct species (C. rufus) that has undergone human-influenced admixture with coyotes. The other is that it was never a distinct species but was derived from past admixture between coyotes and gray wolves, due to the gray wolf ...
The comparison indicated that the red wolf was about 76% coyote and 24% gray wolf with hybridization having occurred 287–430 years ago. The eastern wolf – which was referred to as the "Great Lakes" wolf in this study – was 58% gray wolf and 42% coyote with hybridization having occurred 546–963 years ago.

The taxonomic status of the red wolf is debated. It has been described as either a species with a distinct lineage, [73] a recent hybrid of the gray wolf and the coyote, [10] an ancient hybrid of the gray wolf and the coyote which warrants species status, [74] or a distinct species that has undergone recent hybridization with the coyote.
