The classification system for at-risk species is based on how many animals of a particular species are believed to be alive. It ranges from extinct to least concern. Other rankings include near threatened, vulnerable, endangered and critically endangered.
sperm and egg from separate species are non-compatable.
It creates genetic variation within the species allowing them to adapt to changes in their environment through the process of natural selection. Species without genetic diversity are at a greater risk for unhealthy reproduction because they will have a greater tendency to produce offspring with recessive genetic diseases.

As all the cloned individuals are identical they have exactly the same strengths and weaknesses. If the environment changes rapidly in a way that makes it harder for them to survive then most or even all individuals may be eliminated before any evolved better ways to survive in the changed environment. In species that have other means of reproduction available their populations have greater diversity in strength and weaknesses, so there is a greater chance that some individuals will already be able to better survive in the newly changed environment. Those individuals will pass on their traits to the next generation.

a species whose numbers are so small that the species is at risk of extinction
That they become an invasive species.
At-risk species include those with status under the federal Endangered Species Act and a state’s Endangered Species Act. Other at risk species are those on a state's Fish and Wildlife Department’s sensitive species list, and a state's Department of Agriculture lists. Several other organizations like the World Wildlife Federation have lists that include additional animals that the government has not listed, but the individual organization believes is at risk.
Five categories of risk species include extinct, extinct in the wild, critically endangered, endangered and vulnerable.
