Genetic resistance

Genetic rescue is a conservation biology method that involves introducing genetic diversity into an inbred population. The goal of genetic rescue is to increase the genetic variation and fitness of a population, thereby reducing the risk of extinction.

Overview[edit | edit source]

Genetic rescue is often used in conservation efforts for endangered species. It involves introducing new individuals from a different population into an inbred population. This can increase the genetic diversity of the population, which can lead to increased fitness and survival rates.

Process[edit | edit source]

The process of genetic rescue involves several steps. First, a population that is suffering from inbreeding depression is identified. This is a condition where a population has become so genetically similar that it is suffering from reduced fitness and survival rates.

Next, individuals from a different population are introduced into the inbred population. These individuals bring with them new genetic material, which can increase the genetic diversity of the population.

Finally, the effects of the genetic rescue are monitored. This can involve tracking the survival and reproduction rates of the population, as well as any changes in genetic diversity.

Benefits[edit | edit source]

The main benefit of genetic rescue is that it can increase the fitness and survival rates of a population. This can reduce the risk of extinction for endangered species.

In addition, genetic rescue can also increase the genetic diversity of a population. This can make the population more resilient to changes in the environment, such as changes in climate or habitat.

Risks[edit | edit source]

While genetic rescue can have many benefits, it also comes with risks. One of the main risks is outbreeding depression, which is a decrease in fitness that can occur when individuals from different populations breed. This can occur if the populations are too genetically different, and the offspring are less fit than their parents.

Another risk is the potential for disease transmission. If the individuals introduced into the population carry diseases, they could potentially spread these diseases to the rest of the population.
