10 Questions
explain model B
the genotype increases the effects of the environmental risk but without the environmental risk, there is no disease.
explain model C
(the opposite of model B) the environmental risk factor increases the effect of the genotype on disease development. but without the genotype, there is no disease.
explain model D
both the environmental risk factor and genotype are equally required to cause disease
explain model E
the environmental risk factor and the genotype both have some effect on disease risk, but risk is higher when they occur together than alone
Which of the following best describes a gene-environment interaction?
c) Both genetic and environmental factors contribute to traits, and their effects depend on each other.
In a study investigating gene-environment interactions, researchers find that individuals with a specific genetic variant are more likely to develop a certain health condition when exposed to a particular environmental toxin. What type of gene-environment interaction does this suggest?
c) Interactive
Which of the following factors poses a challenge to reproducibility in gene-environment interaction studies?
a) Complexity of genetic variations
What is a potential consequence of publication bias in gene-environment interaction studies?
b) Overestimation of the strength of gene-environment interactions
Which statistical method is commonly used to assess gene-environment interactions in epidemiological studies?
c) Logistic regression
Epigenetics is considered an underlying mechanism of gene-environment interactions because it involves:
b) Alterations in gene expression without changes to the DNA sequence
