Document Summary

How tall you can grow vs. how tall you actually grow. Lots of genetic programming to be tall theoretically provides an advantage for survival. Avg height now taller due to better nutrition; better able to actually reach genotype potential. Heredity encoded in combos of bases (atgc) these are carriers for protein manufacture. Dominant, recessive, polygenic: dominant shows, recessive will not be displayed unless inherited from both parents, polygenic transmission multiple gene pairs influence phenotype. Human genome project (1990: >75 genes contributing to hereditary diseases have been indentified. Genetic engineering: recombinant dna, gene knockout- particular fxn of gene is eliminated, problem?- few behaviours controlled by single gene. Heritability coefficient- estimate of how much of characteristic is due to genetic factors. Concordance rate: rate of co-occurrence of a characteristic among individuals. Higher rates among those are more related to one another= possible genetic contribution: studied through adoption studies, twin studies, 1. 00 is a perfect correlation.
