    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Domestication and selection in livestock species tend to leave unique genomic imprints in the genome. Under intense selection pressure, these genomic regions show reduction in genetic diversity (runs of homozygosity, ROH). Analysis of ROH provides an informative indicator for inbreeding levels. Using genome-wide SNP data, we analysed six local goat breeds from Uganda to compare the distribution of ROH across different length categories within the breeds with a cut-off threshold of 2Mb. Genomic inbreeding was calculated using an ROH threshold of ≥2Mb for each individual and averaged across the breeds. We further investigated the variation in inbreeding at a higher ROH threshold of 4Mb and compared with the ROH threshold of ≥2Mb. A total of 1,437 ROH segments ≥ 2 Mb were detected with differing frequency and length distribution across the breeds. The Boer breed showed the highest overall frequency. Short ROH (< 8Mb) were generally more frequent than long ROH (> 20Mb). High ROH coverage within the short category may indicate a relatively high contribution of more distant inbreeding in the breeds. Indigenous breeds showed very low levels of genomic inbreeding (with the mean 퐹푅푂퐻 per breed ranging from 0.8% to 2.4%), as compared to higher inbreeding levels in Boer (mean 퐹푅푂퐻 = 13.9%).These findings are useful for providing insights into the demographic history and designing strategies for sustainable breeding programs and conservation strategies for the breeds.
