119 results about "Background selection" patented technology

Background selection describes the loss of genetic diversity at a non-deleterious locus due to negative selection against linked deleterious alleles. It is one form of linked selection, where the maintenance or removal of an allele from a population is dependent upon the alleles in its linkage group. The name emphasizes the fact that the genetic background, or genomic environment, of a neutral mutation has a significant impact on whether it will be preserved (genetic hitchhiking) or purged (background selection) from a population. In some cases, the term background selection is used broadly to refer to all forms of linked selection, but most often it is used only when neutral variation is reduced due to negative selection against deleterious mutations. Background selection and all forms of linked selection contradict the assumption of the neutral theory of molecular evolution that the fixation or loss of neutral alleles is entirely stochastic, the result of genetic drift. Instead, these models predict that neutral variation is correlated with the selective pressures acting on linked non-neutral genes, that neutral traits are not necessarily oblivious to selection. Because they segregate together, non-neutral mutations linked to neutral polymorphisms result in decreased levels of genetic variation relative to predictions of neutral evolution.

Background selection of voltage reference values for performing memory read operations

A storage subsystem implements a background process for selecting voltage reference values to use for reading data from a non-volatile memory array, such as an array of multi-level cell (MLC) flash memory. The process involves performing background read operations using specific sets of voltage reference values while monitoring the resulting bit error counts. The selected voltage reference values for specific pages or other blocks of the array are stored in a table. Read operations requested by a host system are executed using the corresponding voltage reference values specified by the table.
