Which level of biodiversity involves variations within a single population?

Biodiversity is the inconsistency among living organisms from all foundations, including terrestrial, marine, and other aquatic ecosystems.  The answer is Intrapopulation diversity. Intrapopulation variability in resource gaining influences population dynamics, with significant implications for conservation planning. Spatial analyses of niche difference within and among populations can afford relevant information about ecological relations.  

The answer is genetic diversity. This is the total number of variations in the genetic makeup of the individuals in a population. It includes the different alleles of a gene among the individuals of a population. The genetic diversity is also responsible for the genotypic variation across a population when the environment influences the manifestation of genes.
