Neighbour Joining Tree showing relative genetic distance between subgroups from analysis of pedigree data assigned by female ancestry line. The impact of selective breeding on the diversity and structure of the QH breed was evaluated using pedigree analysis and genome-wide SNP data from horses representing 6 performance groups (halter, western pleasure, reining, working cow, cutting, and racing). the observed gene diversity is higher than the expected equilibrium gene diversity (, excess of observed heterozygosity across subpopulations, with the exception of a, in Line 5 to 19.6% in Line 4. Genotype data (36 037 single nucleotide polymorphisms [SNPs]) from 36 Thoroughbreds were also evaluated with those from the 132 performing QHs to evaluate the Thoroughbred's influence on QH diversity. In this study we analyzed the genetic variability in CB horses and investigated its genetic relationships with other horse breeds. However, the results highlight the dependence of the breed on the management of the government-run Cayón stud, which has increased its genetic contribution to the breed over time from 35.6% to 50.1%.

It became popular again in the 1970’s, but now only 550 Cleveland Bay horses exist as of 2006. The Cleveland Bay Horse Society of North America estimates that only around 900 CB purebreds exist globally. The sum of the genetic contributions of the founders to the population revealed that those imported from the ‘Middle East’, Poland, the United Kingdom and Egypt had a higher importance in the formation of the Spanish Arab Horse, contributing, respectively, 36.4%, 18.7%, 11.9% and 9.1% of the genetic variability. that the breeding structure has been changed since the founder generation [54]. positive selection in thoroughbred horses.
