... The Dobzhansky–Muller model was proposed as an alternative to single-gene speciation in which allele A1 is incompatible with allele A2. This scenario is unlikely because the A2A2 genotype cannot evolve from the A1A1 genotype if the heterozygote A1A2 is sterile or inviable. That is, hybrid dysfunctio ...

... What does this have to do with gene therapy? You can think of a medical condition or illness as a "broken window." Many medical conditions result from flaws, or mutations, in one or more of a person's genes. Mutations cause the protein encoded by that gene to malfunction. When a protein malfunctions ...

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.
