Summary A total of 180 mt DNA sequences from hair C aribbean (93), W est A frican (73) and C anarian‐wooled (14) sheep were analysed to shed light on the origin of hair sheep. A comparison of 360 I berian sheep sequences retrieved from G en B ank was performed to assess a possible E uropean origin of the C aribbean hair sheep. These 180 sequences gave 48 different haplotypes (16 in C aribbean sheep). All C aribbean and C anarian‐wooled sequences and 91.8% of the W est A frican samples belonged to haplogroup B . The sheep analysed showed wide haplotypic identity. Caribbean sheep shared roughly two‐thirds of their samples with C anarian‐wooled and W est A frican samples, respectively. Principal component analysis showed that the C aribbean and the C anarian‐wooled sheep clustered together. Additional analyses showed that hair and I berian sheep had wide genetic identity. It was not possible to ascertain a single C anarian, A frican or E uropean origin of the C aribbean hair sheep using mt DNA markers only. European, A frican and C aribbean hair sheep maternal genetic backgrounds likely result from related domestication events.
