Cryptic genetic variation
What is cryptic genetic variation? Cryptic genetic variation refers to unexpressed, bottled-up genetic potential. It is not normally seen, but is expressed under abnormal conditions such as in a new environment or a different genetic background. In a sense, the measurable component of normal variation is just the tip of an iceberg of genetic possibilities that are hidden below the visible surface.
متن کاملSmall- and large-effect quantitative trait locus interactions underlie variation in yeast sporulation efficiency.
Quantitative trait loci (QTL) with small effects on phenotypic variation can be difficult to detect and analyze. Because of this a large fraction of the genetic architecture of many complex traits is not well understood. Here we use sporulation efficiency in Saccharomyces cerevisiae as a model complex trait to identify and study small-effect QTL. In crosses where the large-effect quantitative t...
متن کاملDifferential Regulation of Cryptic Genetic Variation Shapes the Genetic Interactome Underlying Complex Traits
Cryptic genetic variation (CGV) refers to genetic variants whose effects are buffered in most conditions but manifest phenotypically upon specific genetic and environmental perturbations. Despite having a central role in adaptation, contribution of CGV to regulation of quantitative traits is unclear. Instead, a relatively simplistic architecture of additive genetic loci is known to regulate phe...
متن کاملBulk Segregant Analysis Reveals the Genetic Basis of a Natural Trait Variation in Fission Yeast
Although the fission yeast Schizosaccharomyces pombe is a well-established model organism, studies of natural trait variations in this species remain limited. To assess the feasibility of segregant-pool-based mapping of phenotype-causing genes in natural strains of fission yeast, we investigated the cause of a maltose utilization defect (Mal(-)) of the S. pombe strain CBS5557 (originally known ...
متن کاملCryptic Genetic Variation in Evolutionary Developmental Genetics
Evolutionary developmental genetics has traditionally been conducted by two groups: Molecular evolutionists who emphasize divergence between species or higher taxa, and quantitative geneticists who study variation within species. Neither approach really comes to grips with the complexities of evolutionary transitions, particularly in light of the realization from genome-wide association studies...
