Harvey Blackburn notes that animal tissue genebanks are more common than was implied in a recent post.
Perhaps you should be exploring the number of gene banks which are developing comprehensive animal collections that can be used to reconstitute animal populations. Such gene banks have already been established in the U.S. through USDA/Agricultural Research service, Canada, the Netherlands, France, Brazil, Tunisia, Uganda and China.
