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. genetic erosion — European Environment Agency 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. 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 occurs because each individual organism has many unique genes which get lost when it dies without getting a chance to breed. 14. 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. genetic erosion — European Environment Agency 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.

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?

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.
