Friedrich, J., Bailey, R. I., Talenti, A., Chaudhry, U., Ali, Q., Obishakin, E. F., …Wiener, P. (2023). Mapping restricted introgression across the genomes of admixed indigenous African cattle breeds. Genetics Selection Evolution, 55(1), Article 91. https://doi.org/10.1186/s12711-023-00861-8

Background: The genomes of indigenous African cattle are composed of components with Middle Eastern (taurine) and South Asian (indicine) origins, providing a valuable model to study hybridization and to identify genetic barriers to gene flow. In this... Read More about Mapping restricted introgression across the genomes of admixed indigenous African cattle breeds.

Animal performance is an outcome of genetic effects, environmental influences, and their interaction. Understanding the influences of the environment on performance is important to identify the right breeds for a given environment. Agroecological zon...
