PSYC 1115 Chapter Notes - Chapter 4: Twin, Molecular Genetics, Twin Study
Document Summary
Behaviour genetics: genes, twin and adoption studies, temperament and heredity, molecular genetics, heritability, gene/ environment interaction. Dna study how heredity and environment conteibute to human differences threadlike structure made largely of dna molecules siralung, complex molecule containing genes biochemical unit of heredity that make up dna. Provide code for creating the proteins that form our body"s building blocks. Genes direct the assembly of proteins that build the body. Result of complex interaction of genes and countless other molecules. Biological pre t donates half of set to offspring. Behaviour genetics environment study of relative power and limits of genetic and environmental influences on behaviour every nongenetic influence, from prenatal nutrition to people and things around is. Do not always have same number of copies of genes. Not all identical twins share same placenta (environmentally different) separated identical twins adoptive families maintain same genes while testing effects of different home environments maintain home environment while studying effects of genetic differences.
