Answer:
The genetic diversity is increased due to genetic variation.
Step-by-step explanation:
Genetic variation happens due to the mutation random mating, random fertilization and also because of the combination of homologous chromosomes at the time of meiosis. Examples of the genetic diversity is domestic dogs, humans have successfully created the breeds by breeding selectively with traits according to their requirement. Woody plant species, the cheetah etc. Genetic diversity helps in adapting to the changes happening in the environment. This changes happens with modification in alleles.
