Studies on mtDNA and microsatellite loci indicate that wolves have hybridized extensively with coyotes in the northeastern USA and southeastern Canada, with the frequency of coyote haplotypes in wolves tending to increase to the east, from 50% in Minnesota, to 100% in southern Quebec.
Wolves have hybridized extensively with coyotes in the northeastern USA and southeastern Canada. This was with the frequency of coyote haplotypes in wolves. This is what studies on mtDNA and microsatellite loci indicate. These wolves are tending to increase to the east to 100% in southern Quebec. This is from 50% in Minnesota.
