The correct answer is - A. Producing offspring that are genetically identical to the parents
Explanation:
Genetic variation is the difference between the population or individual on a genetic level. If there is a change in the DNA of individuals or among the population, it is genetic variation in these organisms.
There are several factors that result in genetic variation such as random mating, random fertilization, mutation, crossing over during meiosis, and many more. Producing genetically identical offspring to the parents is not a factor as there is no variation is taken place on the genetic level.
