Suppose concordance data were collected from a cohort study of twins to study the genetic contribution to the onset of type 1 diabetes, also called juvenile diabetes. both monozygotic (identical) twins and dizygotic (fraternal) twins who grew up together in the same household were included. the concordance rate was found to be 68 % among monozygotic twin pairs and 11 % in dizygotic twin pairs. what general conclusion about type 1 diabetes can be drawn from these results there is low penetrance of the type 1 diabetes phenotype. therefore, genetic and environmental effects cannot be estimated the heritability of type 1 diabetes is likely high, indicating that genetics plays a larger role no results can be drawn because too many potential variables are present in the study to in the development of type 1 diabetes than the environment. make a reliable conclusion about how twins develop type 1 diabetes. the environment plays a larger role in the development of type 1 diabetes than genetics nhdicanin on herilayitythe development of ype t
