Due to difficulties in retaining
pedigree information during early life-stages these
further reductions in genetic diversity often go unrecognised
and have the potential to manifest themselves in
later generations through increased rates of inbreeding
and the associated negative effects of inbreeding
depression, loss of adaptive fitness and importantly, a
lack of variation for directed selection programs (Doupe
and Recher, 1999; Wang et al., 2002; Liu et al., 2005).
