What is the Biological Significance of Genetic Diversity Between Populations

Question

What is the biological significance of genetic diversity between populations?
A) Genes for adaptive traits to local conditions make microevolution possible.
B) The population that is most fit would survive by competitive exclusion.
C) Genetic diversity allows for species stability by preventing speciation.
D) Isolated populations become more fit.
E) Diseases and parasites are not spread between separated populations.

Accepted Answer

Genetic diversity between populations allows for the existence of different gene pools with variations that may have adaptive traits for specific environmental conditions. This variation enables microevolution to occur, promoting the survival of the fittest individuals or groups within a population.

Answer: B
 Genetic diversity allows for the presence of variation within a population. In a competitive environment, the fittest individuals, which may possess advantageous traits, will outcompete the rest, promoting the survival of the most fit population.

Answer: E
 Separated populations have different selective pressures and exposures to diseases and parasites, leading to differences in their genetic makeup. This diversity can provide a natural barrier to the spread of pathogens and parasites between populations, contributing to the maintenance of genetic diversity in different groups.
