  1. n: Number of animals.
  2. aSum L.: Total length of ROH detected in each population.
  3. bMax, Min.: Maximum and minimum lengths of ROH segments among the total ROH detected.
  4. cMean L.: Average length of ROH, calculated as the total length of ROH (Sum L.) divided by the number of individuals.
  5. dFROH: Proportion of the genome covered by ROH, indicating the inbreeding coefficient based on ROH.
  6. Population: Moghani pure sheep (M), Booroola Merino × Moghani (BMM), Booroola Romney × Moghani (BRM), Texel Dalzell × Moghani (TDM), Texel Tamlet × Moghani (TTM).
