Cryptic genetic variation is enriched for potential adaptations.
Cryptic genetic variation accumulates under weakened selection and has been proposed as a source of evolutionary innovations. Weakened selection may, however, also lead to the accumulation of strongly deleterious or lethal alleles, swamping the effect of any potentially adaptive alleles when they are revealed. Here I model variation that is partially shielded from selection, assuming that uncon...
متن کاملThe population genetic theory of hidden variation and genetic robustness.
One of the most solid generalizations of transmission genetics is that the phenotypic variance of populations carrying a major mutation is increased relative to the wild type. At least some part of this higher variance is genetic and due to release of previously hidden variation. Similarly, stressful environments also lead to the expression of hidden variation. These two observations have been ...
متن کاملEvolutionary Relationships, Population Genetics, and Ecological and Genomic Adaptations of Perch (Perca)
The latest results about the evolutionary, biogeographic, and population genetic relationships of the three species comprising the percid fi sh genus Perca are presented, explained, and discussed. New analyses from new data dated the origin of the genus to an estimated 19.8 million years ago (mya) during the early Miocene Epoch, and the distribution of ancestral Perca likely extended across the...
متن کاملCCL22 16C/A Genetic Variation is not Associated with Breast Carcinoma in Southern Iranian Population
Background: CCL22/MDC is a CC chemokine with a critical role in regulation of the immune balance in physiological condition. CCL22/CCR-4 ligation has been documented to participate in the migration of regulatory T (Treg) cells and Th2 lymphocytes to the site of breast tumors; circumstances that are known to be associated with poor prognosis. Objective: To investigate the association of a single...
متن کاملPopulation genetic inference from genomic sequence variation.
Population genetics has evolved from a theory-driven field with little empirical data into a data-driven discipline in which genome-scale data sets test the limits of available models and computational analysis methods. In humans and a few model organisms, analyses of whole-genome sequence polymorphism data are currently under way. And in light of the falling costs of next-generation sequencing...
