ABSTRACT


The study examines the contribution of founders and ancestors to the active population of Tatra Shepherd dogs whose records are kept in the herdbook of the Krakow Branch of the Polish Kennel Club. Four-generation pedigrees of 34 Tatra Shepherd dogs, 19 males and 15 females, born in 1995–2007, were used as a material for creating pedigrees of 150 individuals of both sexes (66 males, 84 females). The 34 animals forming the active population were treated as a reference population in the founder and ancestor analysis performed to determine the total and effective number of founders and ancestors, and to identify those with the highest gene contribution to the reference population. It was found that the reference population had 54 founders and 30 ancestors in total. The effective numbers of founders and ancestors were 28 and 16, respectively. The group of main founders, i.e. those with highest gene contribution to the active population, was composed of 32 animals (15 dogs and 17 bitches). Five founders (3 males and 2 females) contributed from 4% to over 7% of genes, 13 animals from 2% to 4%, and the others only 1–2%. The group of main ancestor comprised 22 animals (14 males and 8 females). Among those, 5 individuals made the gene contribution from 6% to 15%, and the rest, up to 5.5%. Eight individuals were both main founders and main ancestors.

Key words: effective number of ancestors, effective number of founders, founder contribution, genetic structure, Tatra Shepherd dog.
