PSYC 302 Lecture Notes - Quantitative Trait Locus, Autism Spectrum, Neuroglia
Document Summary
Four fundamental relations: parents" genetic contribution to the child"s genotype, contributions of the child"s genotype to his or her own phenotype, contribution of the child"s environment to his or her own phenotype. Influence of the child"s phenotype on his or her environment. Relation 2: child"s genotype and phenotype: although every cell in your body contains copies of all the genes you received from your parents, only some of those genes are expressed. Gene expression: developmental changes: regulator genes largely control the continuous switching on and off of genes that underlie development across the lifespan, a given gene influences development and behavior only when it is turned on. Polygenic inheritance: when traits are governed by more than one gene, applies to most traits and behaviors of interest to behavioral scientists. Relation 3: child"s environment and phenotype: as the model indicates, the child"s observable characteristics result from the interaction of environmental factors and the child"s genetic makeup.
