Differentiating between Y chromosome sequences in Croatian canids - short communication

Detecting the hybridization between species is important for evolutionary studies of speciation processes, conservation biology and management, but we still lack a general empirical perspective of hybridization problems in canids. Hybridization may occur between many species of the canid family, sometimes threatening the survival of endangered species or populations. Mitochondrial DNA control region haplotypes can be used to discriminate between Croatian wolves, dogs and jackals, and the goal of our research was to identify species specific Y chromosome haplotypes that could be used in detection of paternal origin in possible hybrids. We analyzed three non- overlapping Y chromosome fragments of the grey wolf, golden jackal and dog in the total length of 1, 898 base pairs. Two haplotypes were identified, one shared among grey wolf and dog, and one specific golden jackal haplotype. We did not find polymorphic sites that could be used to distinguish the paternal line in wolf - dog hybrids, but six polymorphic sites were identified that can be used to discriminate golden jackal from grey wolf and domestic dog.
