10 Questions
what are the 3 types of traditional genetic designs?
adoption studies, twin studies and family studies
describe twin studies
twin studies observe the effects of different environments on identical genotypes and the levels of gene expression in different environments
explain adoption studies
adoption studies observe the similarities between adopted children and their biological parents, who do not share the same environment
explain family studies:
family studies compare low-risk controls to high-risk children to determine the environmental effect on subjects with different levels of genetic risk
what are the two types of gene-environment interaction studies?
molecular analyses and traditional genetic designs
what are the 3 methods of molecular analysis in studying gene-environment interaction?
environmental interactions with single gens, environmental interactions with multiple genes and genome-wide association studies
explain the molecular analysis of interactions with single genes
SNPs are compared with single binary exposure factors to determine any effects
explain the molecular analysis of interactions with multiple genes
using polygenic approaches to analyse single environmental factor interactions with multiple genes
explain genome-wide interaction studies
genome-wide interaction studies examine the interaction between the environment and a large number of independent SNPs.
explain model A of a gene-environment interaction
the genotype produces or increases the expression of an environmental risk factor that can also be produced non-genetically
