Inbreeding and relationship are presented in the Beagle dog population as well as the contribution of founders and ancestors to the active population of Beagles recorded in the herdbook of the Cracow Branch of the Polish Kennel Club. From four-generation pedigrees of 84 Beagle dogs (29 males and 55 females) born in 1996-2007, one-generation pedigrees of 611 individuals (267 males and 344 females) were created. The inbreeding (FX) and relationship (RXY) coefficients were estimated for all 611 animals, for each sex separately and between sexes. For the active population of 84 animals, founders and ancestors were determined. Among all the animals, 13.75% (12.36% of males and 14.83% of females) were inbred; about 43% of those belonged to the active population. The mean FX values for all and for inbred individuals amounted to 0.0068 and 0.0492, respectively (0.0070 for all males, 0.0066 for all females, 0.0565 for inbred males and 0.0445 for inbred females). About 12.28% of pairs were related. The mean RXY was 0.0104 and 0.0848 for all and related pairs, respectively ( 0.0095 and 0.0926 in males, 0.0114 and 0.0807 in females, 0.0101 and 0.0853 between sexes. There were total of 222 founders and 54 ancestors. The effective numbers of founders and ancestors were 102 and 26,respectively. There were 29 main founders revealed. Four founders contributed from 2% to approx.3% of genes while the others only 1-2%. Seven out of 34 main ancestors contributed from 4% to over 10% genes, and remaining ones - up to 4%. One individual was both main founder and main ancestor.
