Geographical distribution of cattle populations. Detailed information is showed in Table 1. Map was created using R Project for Statistical Computing v. 3.3.1 (https://www.R-project.org) and packages rworldmap v. 1.3–6 (https://cran.r-project.org/web/packages/rworldmap/index.html), maps v. 3.2.0 (https://cran.r-project.org/web/packages/maps/) and mapproj v. 1.2–5 (https://cran.r-project.org/web/packages/mapproj/index.html). Package rworldmap v. 1.3–6 was used to generate outline and colorful dots while packages maps v. 3.2.0 and mapproj v. 1.2–5 were used to add texts. Different color indicates different geographical regions of population origins.
