Document Summary
At general level, you were either born with a behaviour (nativism-from genes) or you gained it through experience (empiricism-from environment) Behaviour genetics: study of genetic influences on behaviour. Founded by john fuller, john scott and william r. thompson (later chaired. A lot of studies involve family, twin, and adoption studies (identical twins share genome but how they differ depends on environmental cues, adoption studies look at socioeconomic/environmental factors) Cells are controlled by proteins genes = regions of chromosomes that encode (transfer genetic info. From dna to protein) particular proteins (like blueprints for protein prod. ) Genes are located at locus on chromosome. Homozygous: genes at same locus on pair of chromosomes is same; each aren"t. Heterozygous: each parent contributes diff. allele for particular gene. Alleles: pairs of genes at a given locus (alternative forms of same gene) contributes same allele for a particular gene. One inherited by father, other from mother.
