However, the composition of the pathogen community varies, even if individuals belong to the same species and the same population. Ecologists have now shown that these differences are primarily due to genetic variation among the hosts. The loss of genetic diversity could thus render species more vulnerable to infections and extinction.

However, scientists have developed a method of injecting mouse parthenogenotes with sperm that allows them to become healthy baby mice with a success rate of up to 24 per cent.
