Explain how the lacfk of genetic diversity found in populations of endangered species might hinder their recovery
Genetic diversity is needed to cope with environmental changes. With genetic diversity, if there are large changes in the environment, at least some individuals might be able to cope with the changes to insure survival of the species. Without genetic diversity, a change that kills some members of a species is more likely to kill them all.
However, since this is not my area of expertise, I searched Google under the key words "'genetic diversity' 'endangered species'" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
The lack of genetic diversity in populations of endangered species can hinder their recovery in several ways.
1. Reduced Adaptability: Genetic diversity is important for a species to adapt to changes in their environment. It provides a broader range of genetic traits that can help individuals cope with environmental pressures such as habitat loss, climate change, or disease outbreaks. When a population has low genetic diversity, there is a limited pool of genetic traits available to respond to such challenges, making the species more vulnerable to extinction.
2. Increased Inbreeding: In small and isolated populations with low genetic diversity, individuals are more likely to mate with close relatives. This leads to inbreeding, which can have negative consequences for the survival and reproduction of the species. Inbreeding increases the risk of genetic disorders, reduces fertility, and weakens the overall fitness of the population.
3. Reduced Reproductive Success: Low genetic diversity can negatively impact reproductive success. Critical genes involved in reproductive processes, such as those responsible for sperm or egg quality, may be compromised or absent in populations with limited genetic variation. This can result in reduced fertility, lower birth rates, or even reproductive failure, further hampering the recovery of the species.
4. Vulnerability to Disease: Genetic diversity plays a crucial role in the immune response of a species. A diverse gene pool provides a wider range of immune system variations that can effectively combat various pathogens. In populations with low genetic diversity, there is a higher risk of susceptibility to diseases and reduced resistance against pathogens, making them more prone to epidemics or population crashes.
