The theory behind cognitive genomics is based on elements of genetics, evolutionary biology, molecular biology, cognitive psychology, behavioral psychology, and neurophysiology. Intelligence is the most extensively studied behavioral trait. [1] In humans, approximately 70% of all genes are expressed in the brain. [2]
The serotonin transporter gene (SLC6A4) with the 5-HTTLPR is located on chromosome 17.The polymorphism occurs in the promoter region of the gene. Researchers commonly report it with two variations in humans: A short ("s") and a long ("l"), but it can be subdivided further. [4]
An example Gel documentation system, showing the results of gel electrophoresis on a connected monitor.. A gel doc, also known as a gel documentation system, gel image system or gel imager, refers to equipment widely used in molecular biology laboratories for the imaging and documentation of nucleic acid and protein suspended within polyacrylamide or agarose gels.
For humans, the Big Five personality traits, also known as the five-factor model (FFM) or the OCEAN model, is the prevailing model for personality traits. When factor analysis (a statistical technique) is applied to personality survey data, some words or questionnaire items used to describe aspects of personality are often applied to the same person.
In 2013 the American College of Medical Genetics and Genomics (ACMG) recommended that certain genes always be included any time a genomic sequencing was done, and that labs should report the results. [31] DNA studies have been criticised for a range of methodological problems and providing misleading, interpretations on racial classifications.
Genetic analysis can be used generally to describe methods both used in and resulting from the sciences of genetics and molecular biology, or to applications resulting from this research. Genetic analysis may be done to identify genetic/inherited disorders and also to make a differential diagnosis in certain somatic diseases such as cancer .
Molecular genetics is a branch of biology that addresses how differences in the structures or expression of DNA molecules manifests as variation among organisms. Molecular genetics often applies an "investigative approach" to determine the structure and/or function of genes in an organism's genome using genetic screens.
The argument continues that this state of affairs has led to controversies including race, intelligence, instances where variation within a single gene was found to very strongly influence a controversial phenotype (e.g., the "gay gene" controversy), and others. This argument further states that because of the persistence of controversy in ...
