Evidence of subpopulation diversification and traces of introgression within Canarian camel breed zoometric standard: scope and opportunities for selection

Extant diversity for phenotypic traits is an essential criterion to be considered when ordering priorities for conservation and improvement of animal genetic resources. Concretely, the characterisation of the distinctive body morphometry of a particular group of animals can aid in the design of selective breeding programs, given the strong correlation between body morphology and productive function. The present research aims to characterise an endangered autochthonous camel breed (Canarian camel), mainly relegated to leisure riding, for its body morphology, with a double objective: to explore the phenotypic diversity and structure of the breed for zoometric traits and assess the zoometric profile of this genetic resource that supports its differentiation from other camel breeds. Overall, the results highlight the existence of a high degree of diversity, which may be linked to genetic factors for zoometric traits in an endangered autochthonous breed with traditional in situ breeding schemes, which predicts the success of the implementation of genetic improvement schemes for such functional characteristics. This phenotypic diversity in body morphology could also be a tool for the evaluation of new functional niches within the efforts of functional valorisation of this camel breed for its sustainable conservation. Body morphology traits in the studied camel breed are significantly influenced by sex, physiological status and coat colour.
