Question

Why are populations with high levels of genetic diversity more stable than populations with low levels of genetic diversity? OA. Populations with high levels of genetic diversity are more likely to have individuals with traits that help them survive if conditions change Populations with high levels of genetic diversity are less likely to have high levels of variation in alleles Populations with high levels of genetic diversity are more likely to have individuals that will undergo natural selection if conditions change D. Populations with high levels of genetic diversity are less likely to interbreed with other populations B. O C.​

Answer 1

High genetic diversity in populations allows for greater adaptability and stability in the face of environmental changes. This diversity serves as a crucial factor for evolution and adaptation. Conversely, low genetic diversity makes populations more vulnerable to genetic drift and inbreeding depression, leading to instability and reduced survivability.

Step-by-step explanation:

Populations with high levels of genetic diversity are more stable because they are more likely to contain individuals with a variety of traits that can survive changes in environmental conditions. Genetic diversity represents the raw material necessary for evolution and adaptation, allowing species to adjust to new challenges and promoting long-term survival. In contrast, populations with low genetic diversity may not have the necessary range of traits to adapt to new or changing conditions, making them more susceptible to threats such as disease or environmental changes.

Genetic drift impacts small populations disproportionally, as the loss of a few individuals can significantly affect the genetic structure of these populations. Large populations, with more alleles in their gene pool, can better withstand the random effects of genetic drift, preserving their genetic variance over time. The need to conserve genetic diversity is also critical to prevent inbreeding, which can bring forth harmful recessive mutations, leading to conditions such as inbreeding depression.
