FIG 2.

Geographical distribution of the 64 herds included in the study. Point size is proportional to the number of herds (1 to 4) located in the postal code area. Distribution of MapGnt 16 is illustrated in blue, as are the distributions of the two most common genotypes (MapGnt 5 and MapGnt 6, in red and green, respectively). The large blue dotted line circle represents the significant spatial cluster of MapGnt 16, and the small dotted line blue circle represent herds included in the significant spatiotemporal cluster of MapGnt 16.
