Document Summary

Role of genes in life processes: what do genes do, how do they do it? (1) what do genes do, store information required for the synthesis of protein, specifically: each gene stores information about the precise sequence of amino acids that is required to produce a particular protein. Genetic influence on intelligence: heritability: a means of quantifying the amount of genetic influence on phenotypic variability by estimating the proportion of population level variance on a trait that is attributable to genetic differences between individuals. Chapter 3: plot intelligence of twin b against intelligence of twin a, linear trend, can use pearson correlation coefficient to tell how well a line describes a pattern, can predict the intelligence of twin. B: relatively commensurate, some don"t fit the twin pair nicely, more scatter, dispersion of data around that line, concordance is lower than more mz twins.
