Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes. WebProtected area systems need to conserve species in places with suitable habitat that are configured to facilitate gene flow. Since genetic data require considerable resources to obtain, many proxy methods have been developed to generate plans for protected area systems (prioritizations) that facilitate gene flow without needing genetic data. scots wha hae sheet music
