Which level of biodiversity refers to the diversity shown by a single species at the genetic level over its distributional range?

Genetic diversity

The correct answer is Option (1)-Genetic diversity

The level of biodiversity that refers to the diversity shown by a single species at the genetic level over its distributional range is "Genetic diversity."

Genetic diversity refers to the variation in genes within a single species. It is the variety of genetic information contained in the DNA of individuals within a particular species population. Different populations of the same species can exhibit various genetic traits and adaptations due to factors like geographic isolation, migration, and environmental pressures.

For example, within a species of plant or animal, individuals living in different regions may have distinct genetic characteristics that influence their traits, behavior, and adaptability to their local environments. This genetic variation is crucial for the long-term survival and evolution of the species, as it provides the raw material for natural selection and adaptation to changing conditions.

Conserving genetic diversity is essential to maintain the resilience and viability of populations and to ensure the survival of species in the face of environmental changes and threats.
