... The chance that a cross-over will occur between the loci depends on the genetic distance between them. Loci located far enough apart on the same chromosome act as though they are unlinked and produce equal proportions of parental and recombinant gametes. When the loci in a dihybrid cross are linked, ...

... The ESEfinder matrices have been used to show that disruption of ESEs recognized by various SR proteins cause exon skipping in several genes (11-18). In some contexts, ESEfinder appears to be remarkably accurate. For example, using a BRCA1-derived three-exon minigene system, which is very responsive ...

In addition, it has been estimated that 90% of mutations are recessive to wild type in Drosophila.10 This leads us to hypothesize that relatively few genes (⬃5– 10%) will be responsible for the major phenotypic features in a condition like 18q-.

Epistasis



Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually. It was originally a concept from genetics but is now used in biochemistry, population genetics, computational biology and evolutionary biology. It arises due to interactions, either between genes, or within them leading to non-additive effects. Epistasis has a large influence on the shape of evolutionary landscapes which leads to profound consequences for evolution and evolvability of traits.
