Term
| behavioral genetics research questions |
|
Definition
| 1950s- ask questions why are we all different, why are children like their parents, why are children of the same parents so different? what is the variation in the individual and the covariation between relatives? |
|
|
Term
| behavioral genetics methods (humans) |
|
Definition
| twin/family/adoption studies- attempts to ID causal effects as a natural way to control for other genes and environment; ID hereditability (range, i.e. IQ= 50-80%) |
|
|
Term
| behavioral genetics interaction and correlation |
|
Definition
interaction- genetic sensitivity (w/in ind. and at different devl. times)
correlations: active, passive, evocative |
|
|
Term
| behavioral genetics methods (animals) |
|
Definition
| inbred strain comparison, selective breeding- can know how much you influence trait/ genes, can't know this with humans |
|
|
Term
|
Definition
| 1980s- additive, dominant, epistatic |
|
|
Term
|
Definition
| affected individual and family are more likely to have certain gene- mostly small alleles with little effect, many alleles in a single trait, disequilibrium |
|
|
Term
|
Definition
| gene variant exists more in affected than non-affected, specific gene in small region, tend to be indirect (ie blue family are few that are direct) |
|
|
Term
|
Definition
| GWAS0 no selection bias, cost effective |
|
|
Term
| problems with molecular genetics |
|
Definition
| most studies have looked at 5HTTLPR, MOAI, LPR, Taq1A genes, expensive (although getting less expensive) |
|
|
Term
| problems with behavioral genetics |
|
Definition
| heredity is range, not precise number |
