Genetic diversity and signatures of selection in Icelandic horses and Exmoor ponies.

BMC genomics - 8 Aug 2024

Abstract excerpt

BACKGROUND: The Icelandic horse and Exmoor pony are ancient, native breeds, adapted to harsh environmental conditions and they have both undergone severe historic bottlenecks. However, in modern days, the selection pressures on these breeds differ substantially. The aim of this study was to assess genetic diversity in both breeds through expected (HE) and observed heterozygosity (HO) and effective population size...
