PSYB32H3 Lecture Notes - Lecture 3: Gene-Environment Correlation, C. H. Waddington, Twin
Document Summary
Part of stray cats band (brian sessra) Ended up forming new band infusing specializies in xmas songs. Gene-environment interactions (chapter 2 +3) he doesn"t talk about it in class, but need to know it. Genes, the organism, and the environment: what is a gene-environment interaction, waddington"s cannalization principle. Problems with range of reaction: kinship studies. Evocative gene influences: active gene influences, questions about gene-environment interactions. Genotype: one"s genetic endowment- individual genetic- what is encoded in your. Dna: constant over lifetime- cannot change genotype. Phenotype: observable characteristics of individual, phenotype = behavior, a joint function of genotype + environment = phenotype, emerges through interactions with genotype and environment, focus on organisms as they develop. Waddington canalization principle tendency of heredity of genetic influences to restrict development of some characteristics to one of the small ranges of development. Behavior that is strongly canalized develops strongly in that environment.
