Mendel and Heredity
Mendel and Heredity

... As you learned, the units of inheritance that Mendel studied are now called genes. You can think of a gene as a piece of DNA that stores instructions to make a certain protein. Each gene is located at a particular place on a chromosome called a Locus. Just like a house has an address on a street, a ...

... Genotype is the name for the genes an organism has. A dominant allele is one that is expressed in the phenotype even if only one copy is present in the genotype—that is, even if the other allele is an alternative form. A recessive allele is one that is expressed in the phenotype only when two copies ...

(Mendel called genes, “factors.”) • Dominance- if two alleles in a gene pair are different, the dominant allele will control the trait and the recessive allele will be hidden • Segregation - each adult has two copies of each gene-one from each parent.

Understanding how such lineages respond to selection is thus crucial for understanding adaptive evolution in eukaryotes.

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.
