Causes of this erosion are: A narrowing of variation within breeds - breeders require uniformity within a breed e.g. the amount of genetic variability within a popular
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. One of the main causes of genetic erosion is the replacement of local varieties by modern varieties. Other causes include environmental degradation
by. Martin Irestedt. 1,* ,. Per G. P. Ericson. Genetic erosion has negative developmental effects when the modern varieties which replace local varieties are or become inappropriate for the social, economic Genetic erosion is the loss of genetic diversity within a species.
were estimated. genetic erosion has been suggested as the first priority in any major effort to arrest loss of genetic diversity. Generally, nevertheless, many national programs have not regarded quantification of genetic erosion as a high priority, as apparent from the paucity of Genetic erosion (also known as genetic depletion) is a process where the limited gene pool of an endangered species diminishes even more when reproductive individuals die off before reproducing 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 as being used more broadly, as when Genetic erosion term referred as the loss of variability of crop production in the areas of domestication and secondary diversification i.e. centre of origin (Tsegaye and Berg 2007). Genetic variability of a crop population is altered in ways that make negative genetic gain over a period.
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.

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 exist on the concept of genetic A definition of genetic erosion The level and structure of genetic diversity in plant species � whether wild or cultivated � is shaped by the five evolutionary forces of mutation, recombination, migration, genetic drift and selection (natural and artificial). Define genetic erosion. means loss of genetic diversity between and within populations of varieties of the same species over time or reduction of the genetic basis of a species due to human intervention or environmental change; 2019-02-13 genetic erosion in crops. Genetic erosion of cultivated diversity is reflected in a modernization bottleneck in the diversity levels that occurred during the history of the crop.

It can happen fairly quickly — as with a catastrophic event or change in land use that removes large numbers of individuals and their habitat. But it can also occur more gradually and go unnoticed for a long time. Genetic erosion can represent the loss of entire populations Genetic erosion is the disappearance of genes/alleles from gene pool and reduction in the genetic resources of the earth. Twentieth century has witnessed a loss of 75 per cent of genetic diversity Impacts of Genetic Erosion. 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.
