Both of the above-mentioned possible problems are major concerns with
"arking" any sexually reproducing organism. Zoos try to get around this with
meticulously maintained breeding records so they maximize outcrossing to
maintain genetic diversity. If you start with an already endangered species,
by definition the gene pool has probably been pretty thinned out to start
with. One can only hope that by luck a species/population will survive such
a bottleneck.
