Chapter 6 Expanded Notes
... In genetics, we often deal with what is referred to as the wildtype, a sort of generic, all-purpose version of an animal or plant. Something plain that contains the basic traits for that species being studied. A representative sample for that species. However, if there are members of a species with ...

Chapter 4 Heredity and Evolution
... All cells contain mitochondria that convert energy into a form that can be used by the cell. Each mitochondrion contains several copies of a ring-shaped DNA molecule, or chromosome. Animals of both sexes inherit their mtDNA, and all mitochondrial traits, from their mothers. All the variation in mtDN ...

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.
