Abstract
The consideration of the descendance is indispensable in the preservation of endangered animal breeds.The authors compared mitochondrial DNA (mtDNA) control region sequence in three descendant breeds of the extinct Zaupel sheep, firstly. Their investigation was carried out in order to prove the common origin of Waldschaf (Austria), Bovec sheep (Slovenia) and Cikta (Hungary).A total of 118 biological samples were taken from non‐related representatives of the three breeds between 2015 and 2017. A newly designed primer pair was also used to amplify the segment (1180 bp) to be tested.The total number of haplotypes in the whole study population was 49. The majority of which fell into haplogroup B. The significant negative value of the Fu's Fs statistic (Fs statistic = −3.296, p = 0.013) based on haplotype frequencies demonstrated a moderate foreign gene flow. As a novel observation haplogroups C and D appeared in Cikta and Bovec sheep, respectively. The Tajima D‐test value in the entire study population was −0.914 (p > 0.10), meaning that the separation of the three descendant breeds did not cause genetic drift, these are collectively in genetic equilibrium.The genetic information confirmed the common origin of the breeds known from the breed history.
