Chapter 14 Lecture notes - Elizabeth School District
... In the flower-color example, the F1 plants inherited a purple-flower allele from one parent and a white-flower allele from the other. The plants had purple flowers because the allele for that trait is dominant. 4. Mendel’s law of segregation states that the two alleles for a heritable character ...

The Genetic Structure and Evolutionary Fate of Parthenogenetic

They may, however, provide information with far broader consequences. A third objective of this paper, then, is to suggest ...

Nucleotide substitutions and evolution of duplicate genes.

Thus the goal is to compute the number of substitutions per site or number of substitutions per codon. In our search for duplicate genes we used two different ...

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.
