  • a The six spatial subpopulations comprised those from the northwest, midwest, southwest, southeast, northeast, and north.

  • b Analysis of IAS with inclusion of all MLSs sampled within each (sub)population.

  • c Analysis of IAS with inclusion of one MLS per herd within each (sub)population; 11 of the 205 herds had calves harboring different MLSs, and those were removed.

  • d Analysis of IAS with inclusion of one MLS per (sub)population.

  • e Significant linkage disequilibrium (P < 0.05) and VD > L (where VD is the variance of pairwise differentiation and L is the 95% critical value for VD).

  • f ND, not done due to insufficient sample size.
