Genetic erosion is the loss of genetic diversity—often magnified or accelerated by human activities. In native plant populations, genetic erosion results from habitat loss and fragmentation, but it also can result from a narrow genetic base in the original collections or by practices that reduce genetic diversity. Genetic erosion refers to the gradual reduction in genetic variability, in the population of a species, due to elimination of various genotypes. In other words, the loss of genetic diversity caused by either natural or man-made processes is referred to as genetic erosion. loss of genetic diversity between and within populations of the same species over time; or reduction of the genetic basis of a species due to human intervention, environmental changes, etc.

Data, extrapolated and  The loss of variation in crops due to the modernization of agriculture has been described as genetic erosion. The current paper discusses the different views that  Jun 29, 2018 This is remarkable and suggests that genetic variation has been eroded due to habitat loss and consequent population extinction in the  Feb 13, 2019 Within the altercation of global biodiversity, genetic erosion is rarely considered.

Low genetic diversity in a population of wild animals and plants leads to a further diminishing gene pool – inbreeding and a weakening immune system can then "fast-track" that species towards eventual extinction . genetic erosion, we predicted that (a) recent anthropogenic activities will cause contemporary genetic differentiation to differ from his-torical differentiation, (b) lower genetic diversity and connectivity and greater amounts of inbreeding and bottlenecks will be linked to populations at the southern range limit, and (c) caribou will exhibit Översättnings-API; Om MyMemory; Logga in Genetic erosion and in situ conservation of Lima bean (Phaseolus lunatus L.) landraces in its Mesoamerican diversity center -- 9.

Genetic erosion is now so rapid that within 50 years natural habitats will have little to offer plant breeders searching for genetic variability. So far scientists have only looked at about 10% of the earth’s species. Causes of this erosion are: Genetic erosion is an intuitively appealing but poorly defined concept, applied indistinctly to loss of alleles, gene combinations, genomes, or varieties (4, 9). The extent and significance of recent changes in maize genetics are themselves unclear. The loss of variation in crops due to the modernization of agriculture has been described as genetic erosion.
