Additional file 1: Table S1. Description of samples included in the
analyses. This table provides information about the samples used in this
study such as the sample size, samples origin, land of origin and the references
where the sample were previously characterized.
Additional file 2: Figure S1 Graph of the inferred relationships between
24 cattle breeds without adding migration edges. For full definition of
breeds see Additional file 1: Table S1. This graph shows the genetic relationship
of South African cattle breeds in relation to the cattle breeds of
the world before migration edges were sequentially added.
Additional file 3: Table S2. Explained covariance between populations
for the ancestral graph with 10 migration edges. This data shows the
changes in explained covariance between the populations as the number
of migration edges added to the ancentral graph increases. It shows that
after adding 10 migration edges, no significant changes were oberved in
explained covariance.
Additional file 4: Table S3. Some significant f4 statistics for South African
Sanga cattle. This data shows some of the significant f4 statistics and
indicates the presence of gene flow between these breeds.
