MHC-based sexual selection is known to involve olfactory mechanisms in such vertebrate taxa as fish, mice, humans, primates, birds, and reptiles. [1] At its simplest level, humans have long been acquainted with the sense of olfaction for its use in determining the pleasantness or the unpleasantness of one's resources, food, etc.
A locus control region (LCR) is a long-range cis-regulatory element that enhances expression of linked genes at distal chromatin sites. It functions in a copy number-dependent manner and is tissue-specific, as seen in the selective expression of β-globin genes in erythroid cells . [ 1 ]
Locus of control has been linked to political ideology. In the 1972 U.S. presidential election, research of college students found that those with an internal locus of control were substantially more likely to register as a Republican, while those with an external locus of control were substantially more likely to register as a Democratic.

In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...
Julian B. Rotter (October 22, 1916 – January 6, 2014) was an American psychologist known for developing social learning theory and research into locus of control.He was a faculty member at Ohio State University and then the University of Connecticut.
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
Behavioral plasticity is the change in an organism's behavior that results from exposure to stimuli, such as changing environmental conditions. [1] Behavior can change more rapidly in response to changes in internal or external stimuli than is the case for most morphological traits and many physiological traits.
Central place foraging (CPF) theory is an evolutionary ecology model for analyzing how an organism can maximize foraging rates while traveling through a patch (a discrete resource concentration), but maintains the key distinction of a forager traveling from a home base to a distant foraging location rather than simply passing through an area or travelling at random.
