If dizygotic twins have 100% gene sharing ; then why is the risk to type 1 diabetes of one twin being affected to the other one being affected 30-50% . Why would it not be around 80%. I know that type 1 diabetes is 80% controlled by genetics. Would it be due to mutations or something ?? thanks

Dizygotic twins do not share all their genes, Only monozygotic twins do.
