PSYB30H3 Study Guide - Final Guide: Twin, Twin Study, Dark Triad
Document Summary
One gene = 100-several millon of pares of basis/segment of the dna ex 100 pairings of basis to several million runs on the latter. Allele/element: two forms of gene from each parent. Genotype = specific genetic makeup dna, can"t see ex. Phenotype = how genetic makeup is expressed, gene variant (how either allele is expressed), can see ex eye color blue eyes. Genotype-environment interaction: enviro diff effect on ppl depending on their genetics. Genotype-enviro correlation: ppl change enviro & enviro change ppl. Differential exposure of individuals with different genotypes to different environments. Passive: parents provide both genes and environment to children. Ex child"s verbal ability and the number of books in home. Reactive / evocative: parents respond to children depending on the genotype. Ex baby"s liking for cuddling and mother"s cuddling behavior. Active: person with particular genotype seeks out environment. High sensation seekers expose themselves to risky environments. Positive gene enviro correl: conditions favourable for developing.
