A selective sweep associated with heat tolerance in African cattle. a Fixation index (Fst) and linkage disequilibrium values for Bos indicus samples in 20-kb sliding windows with 5-kb steps (top) and the degree of haplotype sharing around heat tolerance QTL (10.71–10.90 Mb region on chromosome 22). Fst is calculated between B. indicus and commercial samples. The major allele in each B. taurus and B. indicus populations is indicated in red. b Structure of the SOD1 gene with exons indicated by vertical bars. A non-synonymous SNP represents p.Ile95Phe and is highlighted in yellow. Haplotype frequencies are indicated by numbers next to each haplotype. In each haplotype, green and beige bars represent alleles 1 and 2, respectively
