Deleted image removed Image Leon Kamin.jpg right thumb 175px Leon Kamin Leon J. Kamin born December 29, 1927 in Taunton, Massachusetts is an United States American psychologist who chaired Princeton University s Princeton University Department of Psychology Department of Psychology in 1968. Kamin s initial contribution to psychology came from his research and documentation of the blocking effect 1969 . He demonstrated that an animal is blocked from associating a stimulus say, a Bell instrument bell with result say, food , if the stimulus is presented simultaneously with another stimulus that the animal already associates with the result. If the dog already associates the whistle with food, then sounding the whistle and ringing a bell when you give it food will not teach it to associate the bell with food. The blocking effect is one of the hallmark effects in the study of associative learning in humans and animals. Kamin has long opposed the idea that significant personal traits are largely heritable. He became skeptical of the claims of Cyril Burt regarding the heritability of IQ , and published his findings in a 1974 book The Science and Politics of IQ . He co authored the controversial book Not in Our Genes 1984 with geneticist Dick Lewontin Richard Lewontin and neurobiologist Steven Rose . This book, championing the radical science movement, attacked sociobiology and evolutionary psychology . Kamin is known in some circles for his position that the IQ Genetics vs environment heritability of IQ could be zero Mackintosh, 1998 He is honorary professor of psychology at the University of Cape Town in South Africa .

A base analog is a chemical that can substitute for a normal nucleobase in nucleic acid s. A common example would be 5 bromouracil 5BU , the abnormal base found in the mutagenic nucleotide analog BrdU. When a nucleotide containing 5 bromouracil is incorporated into the DNA, it is most likely to pair with adenine however, it can spontaneously shift into another isomer which pairs with a different nucleobase , guanine . If this happens during DNA replication, a guanine will be inserted opposite the base analog, and in the next DNA replication, that guanine will pair with a cytosine. This results in a change in one base pair of DNA, specifically a Transition genetics transition mutation .

Unreferenced auto yes date December 2009 Genetic architecture refers to the underlying genetic basis of a phenotype phenotypic Trait biological trait . A synonymous term is the genotype phenotype map , the way that genotypes map to the phenotypes. The genotype phenotype map has been analyzed in terms of several principal axes epistasis, polygeny, pleiotropy, quasi continuity, modularity, phenotypic plasticity, robustness, and evolvability. Epistasis when the alleles at one Locus genetics locus change the phenotypic effects of genetic variation at another locus, the two genes are said to exhibit epistasis in their interactions. Polygeny when multiple genes contribute to a particular phenotypic character, the map is said to possess polygeny . The genetic architecture in cases of polygeny can be further characterized by the spectrum of contributions of the genes, e.g. many genes of small effect vs. few genes of large effect. Pleiotropy when multiple phenotypic characters are affected by a single genetic variation, the map is said to possess pleiotropy . Quasi continuity when small genetic changes map to small phenotypic changes, the map is said to possess Lewontin quasi continuity Lewontin . Modularity when two different phenotypic characters can be mapped to mostly non overlapping sets of genes, the map is said to possess modularity , though this concept is still in flux in the scientific literature. Phenotypic plasticity Plasticity when a single genotype gives rise to a spectrum of phenotypes, the phenotype is said to have plasticity . The plasticity may occur as different phenotypes among different individuals of the same genotype, or different phenotypes within the lifetime of a single individual, or different phenotypes in response to specific environmental conditions. Mutational robustness when the same phenotype occurs in an organism despite a variety of environmental perturbations, it is said to be robust . When the same phenotype is produced despite mutations ... more details

The New World Agriculture and Ecology Group NWAEG is an organization focused on sustainable agriculture , conservation biology , and social justice . History Originally known as the New World Agriculture Group, NWAEG pronounced new ag first became active in the 1980s. NWAEG is often said to have drawn inspiration from the 1970s Science for the People movement Harvard ecologist Richard Levins made key contributions to both groups. NWAEG s best known project was an intensive effort to provide agricultural research and extension services to the Nicaragua n people during the Sandinista era. Cuba and Chiapas , Mexico are locations of other past and present NWAEG projects, exemplifying the group s informal focus on Latin America . Besides Levins, other prominent members of NWAEG include Richard Lewontin and Michael K. Dorsey .

Orphan date April 2010 Image Double crossover.png frame right DNA segment with three genes, showing a double recombination event. If the individual recombination rates between A and B and between B and C are known, then the c.o.c. between the regions AB and BC can be calculated from the rate of double recombination. In genetics, the coefficient of coincidence c.o.c. is a measure of interference in the formation of chromosomal crossover s during meiosis . It is generally the case that, if there is a crossover at one spot on a chromosome, this decreases the likelihood of a crossover in a nearby spot. ref name itga Anthony J. F. Griffiths Griffiths AJF , Susan R. Wessler Wessler SR , Richard Lewontin Lewontin RC , Sean B. Carroll Carroll SB 2008 Introduction to Genetic Analysis . New York W. H. Freeman and Company. ref This is called interference. The coefficient of coincidence is typically calculated from recombination rates between three genes. If there are three genes in the order A B C, then we can determine how closely genetic linkage linked they are by frequency of recombination. Knowing the recombination rate between A and B and the recombination rate between B and C, we would naively expect the double recombination rate to be the product mathematics product of these two rates. The coefficient of coincidence is calculated by dividing the actual frequency of double recombinants by this expected frequency ref name itga c.o.c. actual double recombinant frequency expected double recombinant frequency Interference is then defined as follows ref name itga interference 1 c.o.c.

John Lee Jack Hubby March 19 1932, Clovis, New Mexico March 28, 1996, Santa Fe, New Mexico was an United States American geneticist, pioneer of gel electrophoresis and co author with Richard Lewontin of foundational studies in the field of molecular evolution . After earning a PhD from the University of Texas in 1959, Hubby took a postdoctoral fellowship at the University of Chicago , followed a faculty position there. In the early 1960s, he developed new applications for gel electrophoresis. He applied the technique to identify different version of the same protein reflecting different allele s for the same genetic locus in fruit flies. Hubby collaborated with Lewtontin to produce two breakthrough papers in 1966 that used electrophoresis to determine the level of genetic variation in natural populations of Drosophila pseudoobscura . Their studies revealed high levels of heterozygosity relative to the predictions of most evolutionary theorists. ref http chronicle.uchicago.edu 960425 obithubby.shtml Obituary John Hubby, BSD , Chicago Chronicle , April 25, 1996, Vol. 15, No. 16.

Summary Information Description Some background info, from a highly verified source As natural historians and human geographers mostly from Europe ventured into Asia, Africa, Australia, and the Americas and began to study the indigenous human populations in detail, maps depicting the worldwide distribution of human skin color were slowly assembled. The best known of these maps is that composed by the Italian geographer Renato Biasutti, which was based on the von Luschan skin color scale. This map has gained broad circulation in several widely distributed publications Barsh 2003, Lewontin 1995, Roberts 1977, Walter 1971 , despite the fact that, for areas with no data, Biasutti simply filled in the map by extrapolation from findings obtained in other areas Robins 1991 . A more accurate and exhaustive compilation of the skin colors of indigenous peoples based only on published skin reflectance measurements is now available Jablonski & Chaplin 2000 . Source Nina G. Jablonski, THE EVOLUTION OF HUMAN SKIN AND SKIN COLOR, Annu. Rev. Anthropol. 2004. 33 600. The improved map is in Jablonski NG, Chaplin G. 2000. The evolution of skin coloration. J. Hum.

I recolored it in accordance with Image Felix von Luschan Skin Color Chart.JPG. The original map was off since it made up red and green colors to distinguish human skin color.
