However, there is a low probability that some of these may in fact be due to the presence of the residual introgressions of CS chromatin on chromosomes other than 2B.
Strategies for introgression depend on the reproductive biology and genetics of each crop and the available exotic germplasm.
Being the major entry point of cattle to Africa, the genetic landscape of the current cattle populations in Ethiopia could have been shaped by several introductions of zebu cattle and introgression of the taurine from the Near-East [7].

Also, they found two wild populations in SEYUC with wild-domesticated introgression characteristics (Table 2).
