Genetic diversity within a species is influenced by a number of variables.
- Mutations, which arise when DNA gene sequences alter, are one source of genetic diversity.
- Another source is gene flow, which is the transfer of genes across species.
- Finally, sexual reproduction might lead to the development of unique genetic combinations, resulting in genetic diversity.
- Genetic diversity among a group of species allows certain organisms to flourish in their environment better than others.
- The degree to which organisms are adapted to life in a particular environment can vary substantially even within a small group of creatures.
- One example is moths of the same species with varying colouring wings.
