Genetic erosion is the loss of genetic diversity—often magnified or accelerated by human activities. It can result from habitat loss and fragmentation, but it also can result from a narrow genetic base in the original populations or collections or by practices that reduce genetic diversity. Genetic erosion is the loss of genetic diversity within a species. It can happen very quickly, due to catastrophic events, or changes in land use leading to habitat loss. But it can also occur more gradually and remain unnoticed for a long time.

Gradual loss of genes or genetic erosion leaves our species of plants and animals vulnerable to new environmental and biotic challenges and causes heavy damage to the society. The Irish Potato famine was a dramatic example of the dangers of genetic uniformity. The Irish population had reached about 248.5 million by 1845. Genetic Erosion: 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: http://www.theaudiopedia.com What is GENETIC EROSION? What does GENETIC EROSION mean?

Genetic erosion

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.

It occurs because each individual organism has many unique genes which get lost when it dies without getting a chance to breed. 14. Concerns about genetic erosion resulted in the initiation of a global network of genebanks to conserve agriculturally important genetic resources. In the agricultural sphere, there is ongoing concern and attention to genetic erosion at all levels, including the Food and … Genetic erosion is a process whereby an already limited gene pool of an endangered species of plant or animal diminishes even more when individuals from the surviving population die off without getting a chance to meet and breed with others in their endangered low population.The term is sometimes used in a narrow sense, such as when describing the loss of particular alleles or genes, as well Genetic erosion in small populations, owing to fragmentation of natural habitats, is expected to obstruct such adaptive responses: (i) genetic drift will cause a decrease in the level of adaptive genetic variation, thereby limiting evolutionary responses; (ii) inbreeding and the concomitant inbreeding depression will reduce individual fitness and, consequently, the tolerance of populations to The term genetic erosion is sometimes used in a narrow sense, such as for the loss of alleles or genes, as well as more broadly, referring to the loss of varieties or even species. The major driving forces behind genetic erosion in crops are: variety replacement, land clearing, overexploitation of species, population pressure, environmental degradation, overgrazing, policy and changing agricultural systems. http://www.theaudiopedia.com What is GENETIC EROSION?

Genetic erosion in agricultural and livestock is the loss of biological genetic diversity – including the loss of individual genes, and the loss of particular recombinants of genes (or gene complexes) – such as those manifested in locally adapted landraces of domesticated animals or plants that have become adapted to the natural environment in which they originated. Genetic Erosion Finger and foxtail millets. Mani Vetriventhan, Shailesh Kumar Singh, in Genetic and Genomic Resources for Grain Chickpea. Shivali Sharma, The major factors responsible for genetic erosion include replacement of the Grass Pea. Shiv Kumar, 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. Genetic Erosion Ecotoxicology, Genetic☆.
