What is an example from the real world where lowered genetic diversity is impacting a species' ability to survive?

How about the Tasmanian Devil.

One example from the real world where lowered genetic diversity is impacting a species' ability to survive is the case of the cheetah (Acinonyx jubatus).

To understand how this is impacting their survival, let's explore how to get the answer:

1. Start by researching the cheetah population and understanding genetic diversity: Begin by researching the cheetah population and understanding the concept of genetic diversity. Genetic diversity refers to the variation in genes within a population and indicates the overall health and adaptability of a species.

2. Explore the causes of low genetic diversity in cheetahs: Investigate the reasons behind the low genetic diversity in cheetahs. The cheetah species have experienced several population bottlenecks throughout history, resulting in a limited gene pool. This reduction in genetic diversity can lead to harmful genetic disorders and reduced adaptability to changing environmental conditions.

3. Look for specific consequences: Examine the consequences that low genetic diversity has on cheetahs' survival abilities. Due to the limited gene pool, cheetahs suffer from reduced immune function and increased vulnerability to diseases. They also face challenges in adapting to changing habitats and finding suitable mates, which can result in reduced reproductive success.

By following these steps, you can learn more about the cheetah's situation and how their lowered genetic diversity is impacting their ability to survive in the real world.
