Document Summary
Cultural inheritance: environmental and social condiions, parental/societal inluences on growth, maturaion and performance, opportunity to reach geneic potenial. Biological inheritance: inluence of parental generaion on ofspring = geneic inluence, 23 chromosomes, 3 billion base pairs, humans share 99. 9% of common geneic back group, less than 0. 1% variaion in geneic makeup accounts for individual uniqueness. Geneic informaion: speciies sequence of amino acids, protein synthesis. Genotype and environment phenotype: sensiivity, determines if we reach geneic potenial or not. Phenotypes measures on a coninuous scale: height and weight, can"t measure phenotype, only the output of it. Twin studies: correlaion average/coeicient is about 0. 7. R-value: % of variaion we can explain, usually about 49% (0. 7x0. 7) Dz: share 50% geneic, correlaion then drops to 0. 3 because it explains only about 10% variaion (r^2) Drops of with cousins, share less than 25% of geneic factors. Helps with counselling families with a disorder that"s geneic, likelihood of having baby with a disorder.
