Data from: Genetic evidence for multiple events of hybridization between wolves and domestic dogs in the Iberian Peninsula
Hybridization between wild species and their domestic counterparts may represent a major threat to natural populations. However, high genetic similarity between the hybridizing taxa makes the detection of hybrids a difficult task and may hinder attempts to assess the impact of hybridization in conse...

Hybridization between wild species and their domestic counterparts may represent a major threat to natural populations.
