production). All bovinan hybrids produce sterile males and fertile females following Haldane's rule. In addition for the agricultural purposes, bovin hybridization was used in the past to save several species such as the American bison in the past. This has caused problems for wild cattle conservation as hybrids pollute the genetic diversity of genetically-pure animals. Bovin hybridization was also a major factor behind the evolution of Bovini, as some species have evidence of ancient hybridization in their genome.
