Abstract

Cilj ovog istraživanja je modelirati broj bioloških populacija istočnojadranskih pasmina ovaca i njihovih prostornih granica u svrhu očuvanja genetskih resursa. Geneland paketom u R programu, provedene su dvije skupine analiza, za 13 pasmina istočnojadranskih ovaca iz Hrvatske, Slovenije i Bosne i Hercegovine temeljem 28 mikrosatelitska biljega i za 14 pasmina temeljem 7 biljega. Obje skupine uključuju četiri modela, testiranih za 1 do 18 bioloških klastera, kroz 10 ponavljanja za svaki set iteracija. Prostorni model s pretpostavkom korelacije alelnih frekvencija temeljem 28 biljega najbolje objašnjava podatke. Belokranjska pramenka ima svoj genetski klaster, istarske ovce i istarske pramenke klasteriraju zajedno. Dalmatinska pramenka svrstava se u dva klastera. Eventualno ukidanje reproduktivne barijere istarskih ovaca i istarskih pramenki preporučljivo je tek nakon analize usklađenosti uzgojnih ciljeva i dodatnih genetskih analiza talijanskog dijela povijesne populacije.

Abstract (english)

The aim of this research is to model the biological population of Eastern Adriatic breeds of sheep and their spatial borders in order to preserve genetic resources. The geneland package in the R programme resulted in two groups of analyses: for 13 breeds of eastern Adriatic sheep from Croatia, Slovenia and Bosnia and Herzegovina based on 28 microsatellite markers and for 14 breeds based on 7 markers. Both groups include four models, tested for 1 to 18 biological clusters, through 10 repetitions. The spatial model with the assumption of correlation of allele frequencies based on 28 noters best explains the data. Belokranjska Pramenka has its genetic cluster, Istrian sheep and Istrian Pramenka cluster together. The Dalmatian Pramenka is divided into two clusters. Possible removal of the reproductive barrier of the Istrian types is recommended only after an analysis of the harmonization of breeding goals and additional genetic analyses of the Italian part of the historical population.
