What is the biological significance of genetic diversity between populations?

Question

Quizplus · Accepted Answer

Genetic diversity allows for the presence of different traits that may be advantageous in different environments. This can lead to natural selection and the evolution of populations that are better adapted to their specific conditions. Without genetic diversity, there would be no variation for natural selection to act upon, and populations would be more vulnerable to environmental changes.

Answer: B
 Genetic diversity contributes to variation in the traits of individuals within populations. This often results in competition between individuals for resources and mates, with the most fit individuals being more likely to survive and reproduce. Over time, this can lead to the exclusion of less fit individuals from the population, resulting in a more homogeneous population.

Answer: E
 Genetic diversity can contribute to variation in immune responses, which can impact susceptibility to diseases and parasites. However, genetic diversity is not the only factor that determines disease susceptibility, and isolated populations may still be vulnerable to disease outbreaks if the pathogen is introduced from another population.
