|When it comes to recovering a species that is threatened in the wild, genetic diversity is a major factor to look at. A lack of genetic diversity puts the entire population at risk because it causes future generations to become weaker. It may increase the mortality rates of offspring, and a “genetic bottleneck” can occur – which means that they lose valuable genetics in the gene pool.
We see this in both isolated populations due to habitat fragmentation, and in populations that are very low overall, like with Mexican wolves.
