Assessment of genetic diversity using characteristics based on probability of gene origin in Slovak Spotted breed

Abstract

The aim of this study was to assess the diversity characteristics based on probability of gene origin in Slovak Spotted breed. The animals were divided into 3 groups by breed types: group  S₀ where the ration of the other then Slovak Spotted breed was ˂ 12.5%; group S₁ =12.5 - 25%; group S₂ = 25-50%.  The reference population of these groups consisted of 17355; 6251 and 12683 individuals, respectively. The pedigree information was available from the Breeding Services of the Slovak Republic, s. e. Total number of founders (f) ranged from 10484 for the S₁ to 20402 for the S₂, the effective number of founders (f_e) ranged from 265 for the S₀ to 507 for the S₂, the effective number of ancestors (f_a) ranged from 69 for the S₀ to 112 for the S₂ and founder’s genome equivalent (f_g) ranged from 41.71 for the S₀ to 70.75 for the S₂. The most important ancestor EGE 003 originating from Slovakia explained 5.30 % of genetic diversity in purebred Slovak Spotted population. The results derived from probabilities of gene origin indicate, that the genetic diversity within each group was still relatively large.
