Finland’s Biodiversity Action Plan comprises eleven actions for genetic diversity (actions 86–96). Mutation of genes, genetic drift and gene flow are also responsible for genetic diversity. For example, in the species of human beings, each human shows a lot of diversity in comparison to another human. Genetic diversity is the variation of heritable characteristics present in a population of the same species. Apart from animal and plants, there are so many microorganisms also which are not visible by the naked eyes. Biodiversity—short for biological diversity—is the variety of all living things and their interactions. Whilst the former will continue to live in the environment Biodiversity encompasses the genetic variety within each species and the variety of ecosystems that species create. of roses.
