Nature something you"re born with vs. nurture something we learn. Genes: strand- like molecules of dna: linked on chromosomes, karyotype: genetic blueprint. Humans: 23 pairs, 22 autosomes + sex chromosomes, xx female, xy- male, y is shorter than x. Genes (dna) codes for rna codes for protein molecules (sequence of amino acids) The influence of genes is through protein synthesis there are no genes for a particular attribute. Gene for intelligence: reaction time factor in intelligence as we measure it. So why not just answer nature if genes code for things: environment can influence protein synthesis as well. Diet: genes determine range of possibilities but not degree of expression. Phenotype: outward expression of genotype (characteristics, behaviors, etc. : can not infer genotype from phenotype, outward characteristics may not indicate underlying genetic contribution.
