How do introgression events shape the partitioning of diversity among breeds: a case study in sheep.

摘要: Background From domestication to the current pattern of differentiation, domestic species have been influenced by reticulate evolution with multiple events migration, introgression, and isolation; this has resulted in a very large number breeds. In order manage these breeds their genetic diversity, one must know structure populations relationships among these. This paper presents results diversity analysis on an almost exhaustive sample sheep reared France. Molecular characterization was performed set 21 microsatellite markers collection 49 that include five breed types: meat, hardy dairy, high prolificacy patrimonial
