Questions and Answers

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 Signup and view all the answers
