A recent study has highlighted the importance of genetic rescue to mitigate the impacts of inbreeding depression in tiger populations of Ranthambore National Park by recommending its use to restore genetic diversity and reduce extinction risks.
About the Genetic rescue:
- The Genetic rescue involves wildlife managers moving individuals from a larger, healthier population to a smaller one to introduce new genetic variation and bolster the population size, aiming to offset inbreeding and lost genetic variation.
- While it can yield positive outcomes by overcoming risks of genetic load and enhancing the population of endangered species.
- The technique’s effectiveness depends upon several factors, including the magnitude and duration of gene flow, along with both genetic and non-genetic factors affecting population dynamics, indicating that it can lead to both beneficial and disastrous effects.
