geenivarantojen

Geenivarantojen refers to the total genetic diversity present within a species. It encompasses all the different gene versions, or alleles, that exist within a population and across its geographical range. A large gene pool is crucial for a species' ability to adapt to changing environmental conditions, such as new diseases, climate shifts, or resource availability. When a population has low genetic diversity, it may be more vulnerable to extinction because individuals are less likely to possess traits that allow them to survive and reproduce under new pressures.

Factors that can reduce gene pools include habitat fragmentation, population bottlenecks (a sharp reduction in population size), and selective breeding in domesticated species. Conservation efforts often focus on maintaining and increasing gene pools by protecting diverse habitats, managing populations to prevent excessive inbreeding, and sometimes through captive breeding programs that reintroduce genetic variation. Understanding and preserving gene pools is a fundamental aspect of biodiversity conservation.
