Evolution and Natural Selection
... caused by the environment is not heritable, so it is not subject to natural selection. However, the ability of organisms to develop differently in different environments can be genetic. This means organisms can evolve to be flexible. Plants are a good example of this. The number of leaves, growth pa ...

Mutations & DNA Technology Worksheet
... Mutations are changes in DNA. Somatic mutations occur in non-reproductive cells and won't be passed onto offspring. Mutations that occur in reproductive cells like eggs and sperm (germ-line mutations) can be passed onto offspring. Effects of germ line mutations: A single germ line mutation can have ...

Inheritance of Traits
... Since Mendel’s time, our knowledge of the mechanisms of genetic inheritance has grown immensely. For instance, it is now understood than inheriting one allele can, at times, increase the chance of inheriting another or can a affect how and when a trait is expressed in an individual's phenotype. Like ...

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.
