	The Correlation Between Relatives on the Supposition of Mendelian Inheritance - Wikipedia, the free encyclopedia
		The Correlation Between Relatives on the Supposition of Mendelian Inheritance is a scientific paper by R.A. Fisher which was published in the Philosophical Transactions of the Royal Society of Edinburgh in 1918, (volume 52, pages 399–433).
		In it, Fisher puts forward a genetic model that shows that continuous variation amongst characters could be the result of Mendelian inheritance.

		This issue was finally resolved by Ronald Fisher, who in 1918 produced a paper entititled "The Correlation Between Relatives on the Supposition of Mendelian Inheritance", which showed using a model how continuous variation could be the result of the action of many discrete loci.
		According to the modern synthesis as established in the 1930s and 1940s, genetic variation in populations arises by chance through mutation (this is now known to be due to mistakes in DNA replication) and recombination (crossing over of homologous chromosomes during meiosis).
		Evolution consists primarily of changes in the frequencies of alleles between one generation and another as a result of genetic drift, gene flow and natural selection.

		The fact that Pearsonian correlations reflect only the linear component of the relationship between two variables is no problem for factor analysis in the abilities domain, because it is rare that mental tests of any kind show any significant nonlinear components in their relationship, and the linear component is always by far the largest.
		Since it has proved impossible to construct a battery of mental tests that are not all positively correlated with one another, thereby yielding a general factor, g, test constructors often attempt to maximize the one feature of their test battery that makes for a high g loading of the tests' composite score.
		It is tantamount to saying that the heritability of any variable cannot be inferred from the pattern of various kinship correlations (from MZ twins to genetically unrelated children reared together) when the correlations are based on sets of kin reared together and reared apart from infancy.

		The low phenotypical correlation was explained by the modest heritability for rearing (0.25 Vs 0.53 for the IIPMF [10]) and by the fact that the (low) environmental correlation had a sign opposite to that of the genetic correlation.

	3 Genetic, Factor, and Path Analysis
		The conflict between those, like Karl Pearson, who followed a Galtonian model of inheritance and those, like Bateson, who adopted a Mendelian model, is well known to students of genetics.
		Charles Spearman, adopting Galton's idea that a correlation between variables might reflect a common underlying causal factor, began to explore the pattern of correlations between multiple measures of ability.
		Wright, on the other hand, was less concerned with providing a theory which could integrate two views of genetic inheritance than he was with developing a method for exploring ways in which different causal hypotheses could be expressed in a simple, yet testable, form.

	Heredity - Enpsychlopedia
		Charles Darwin proposed a theory of evolution in 1859 and one of its major problems was the lack of an underlying mechanism for heredity.
		The inheritance of acquired traits was shown to have little basis in the 1880s when August Weismann cut the tails off many generations of mice to find that their offspring did continue to develop tails.
		It was initially assumed the Mendelian inheritance only accounted for large (qualitative) differences, such as those seen by Mendel in his pea plants — and the idea of additive effect of (quantitative) genes was not realised until Ronald Fisher's (1918) paper on The Correlation Between Relatives on the Supposition of Mendelian Inheritance.

	1 Introduction and Description of Terminology
		It is these effects, based on the principles of Mendelian genetics, that give our structural models a degree of validity quite unusual in the social sciences.
		In this way, the categories of Mendelian genetics that lead to binomial distributions for traits in the population tend toward continuous distributions such as the normal curve.
		This polygenic model was originally developed by Sir Ronald Fisher in his classic paper ``The correlation between relatives on the supposition of Mendelian inheritance'' (Fisher, 1918), in which he reconciled Galtonian biometrics with Mendelian genetics.

		Fisher triumphantly shows that Mendelian segregation results in the maintenance of variation and solves what Darwin himself viewed as the major outstanding diffculty with his theory.
		Thus, genetics is never out of the frame—the question is whether genetics itself is the focus of attention, or whether it is playing a crucial but supporting role in the exploration of evolutionary biology.
		The difference between evolutionary biology and genetics can be illustrated, literally, from the editions of The Genetical Theory of Natural Selection, Fisher’s main opus in evolutionary biology.

		The mechanism of darwin + modern evolutionary synthesis inheritance wasn't discovered in Darwin or Wallace's time, however, so the debate was never settled.
		A critical link between experimental biology and evolution, as well as between Mendelian genetics, natural selection, and the chromosome theory of inheritance, arose from T. Morgan's work with the fruit fly Drosophila melanogaster.
		By that time, most biologists accepted that genes situated linearly on chromosomes were the primary mechanism of inheritance, although how this could be compatible with natural selection and gradual evolution remained unclear.

	Quantitative traits.
		The latter apparently believed that Mendelian segregation was incompatible with the inheritance of QTs (continuously varying characters, to use the jargon of the day).
		In 1904 Pearson gave an analysis of the inheritance of QTs which led him to believe that Mendelian segregation could not explain observed correlations of about 1/2 between parent-offspring QT values such as stature.
		We need to calculate the correlation between QT values of a father and a son, so let's begin by assuming that fathers have genotypes QQ, Qq and qq in the proportions just mentioned, and that mothers also have these genotypes with the same frequencies, independently of their husband's genotype.

		It was not until 1918 that Fisher, in what was probably his most important theoretical paper, demonstrated that Mendelian inheritance of multiple interacting hereditary elements predicts precisely the patterns of transmission and correlation of continuous traits that are observed.
