As of 2010, proposals were in place for the funding of a study of porcine genetics, including variability and relationships among breeds, with the aims of maintaining genetic variability among rare pig breeds and releasing a definition of heritage pork.
As a consequence of increasing limitations to maintaining genetic variability in endangered wildlife species, methods of assisted reproduction widely used in domestic animals are being applied to nondomestic species.
Therefore, outcrossing and increased heterozygosity will play an important role in maintaining genetic variability in plant populations, as suggested by Anderson and Stebbins [4], Stebbins [54], Barton [2], and Stewart et al. [3].
Maintaining genetic variability and avoiding inbreeding are of great importance in the management of small animal populations.
The highly polymorphic and multiallelic SSRs [ 6] are potentially involved in genome evolution by creating and maintaining genetic variability [ 2, 7, 8].
To increase profitability and sustainability while maintaining genetic variability in the cultured stock, the development of genetic breeding programs, such as marker- and gene-assisted selection, is urgently required.
