Heterozygosity (A) and runs of homozygosity (ROH, B) among native UK sheep breeds. Heterozygosity was calculated as the proportion of sites at which an individual is heterozygous after filtering for genotyping call rate and minor allele frequency. Asterix (*) indicates breeds on the UK BAR list. Both heterozygosity and ROH are shown by individual and averaged by breed (black bar)
