Offspring may be more susceptible to disease because they are genetically identical

Explanation:

Asexual reproduction is the process that includes the production of progeny from a single parent. Since there is no gametic fusion and the only single parent is involved, the progeny is genetically identical to the parents and among themselves.  

Some of the genetic variations produced during sexual reproduction are beneficial and increase the survival chances of individuals by making them better adapted to surroundings or imparting beneficial traits such as disease resistance.  

Lack of genetic variations among the progeny makes them more likely to get infected with diseases.
