Genetic correlation. In multivariate quantitative genetics, a genetic correlation (denoted or ) is the proportion of variance that two traits share due to genetic causes, [1][2][3] the correlation between the genetic influences on a trait and the genetic influences on a different trait [4][5][6][7][8][9] estimating the degree of pleiotropy or ...
The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals. The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921. The measure is most commonly used in genetics and genealogy.
Life chances. Life chances (Lebenschancen in German) is a theory in sociology which refers to the opportunities each individual has to improve their quality of life. The concept was introduced by German sociologist Max Weber in the 1920s. [1] It is a probabilistic concept, describing how likely it is, given certain factors, that an individual's ...
The genetics of social behavior is an area of research that attempts to address the question of the role that genes play in modulating the neural circuits in the brain which influence social behavior. Model genetic species, such as D.melanogaster (common fruit fly) and Apis mellifera (honey bee), have been rigorously studied and proven to be ...
Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct , and that using it as a proxy for genetic differences among populations is misleading.
F. Galton, Galton. Sir Francis Galton FRS FRAI (/ ˈɡɔːltən /; 16 February 1822 – 17 January 1911) was a British polymath and the originator of eugenics during the Victorian era; his ideas later became the basis of behavioral genetics. [1][2] Galton produced over 340 papers and books.
Theory of generations (or sociology of generations) is a theory posed by Karl Mannheim in his 1928 essay, "Das Problem der Generationen," and translated into English in 1952 as "The Problem of Generations." [1] This essay has been described as "the most systematic and fully developed" and even "the seminal theoretical treatment of generations ...
The Pearson product-moment correlation coefficient, also known as r, R, or Pearson's r, is a measure of the strength and direction of the linear relationship between two variables that is defined as the covariance of the variables divided by the product of their standard deviations. [4] This is the best-known and most commonly used type of ...
