In 2017, the first reference genome of the wolf Canis lupus lupus was mapped to aid future research. [61] In 2018, a study looked at the genomic structure and admixture of North American wolves, wolf-like canids, and coyotes using specimens from across their entire range that mapped the largest dataset of nuclear genome sequences against the ...
Captive-bred F 1 gray wolf × coyote hybrids, Wildlife Science Center in Forest Lake, Minnesota. A coywolf is a canid hybrid descended from coyotes (Canis latrans), eastern wolves (Canis lycaon), gray wolves (Canis lupus), and dogs (Canis familiaris). All of these species are members of the genus Canis with 78 chromosomes; they therefore can ...
Its size is intermediate between the coyote (Canis latrans) and gray wolf (Canis lupus). [8] The red wolf's taxonomic classification as being a separate species has been contentious for nearly a century, being classified either as a subspecies of the gray wolf Canis lupus rufus, [9] [10] or a coywolf (a genetic admixture of wolf and coyote ...

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]
In 2016, the Committee on the Status of Species at Risk in Ontario recognized the Algonquin wolf as a Canis sp. (Canis species) differentiated from the hybrid Great Lakes wolves which it found were the result of "hybridization and backcrossing among Eastern Wolf (Canis lycaon) (aka C. lupus lycaon), Gray Wolf (C. lupus), and Coyote (C. latrans)".
In recent history, the taxonomic status of the red wolf has been widely debated. Mech (1970) suggested that red wolves may be fertile hybrid offspring from gray wolf (Canis lupus) and coyote (C. latrans) interbreeding. Wayne and Jenks (1991) and Roy et al. (1994b, 1996) supported this suggestion with genetic analysis.
The taxonomic classification of Canis lupus in Mammal Species of the World (3rd edition, 2005) listed 27 subspecies of North American wolf, [7] corresponding to the 24 Canis lupus subspecies and the three Canis rufus subspecies of Hall (1981). [1] The table below shows the extant subspecies, with the extinct ones listed in the following section.
