Interference is defined as the degree to which crossovers at one position inhibit crossovers at nearby positions. The coefficient of coincidence is the ratio of observed double crossovers to expected double crossovers. Interference is calculated as 1- (observed double crossovers/expected double crossovers). Therefore, D is the correct choice as interference is equal to one minus the coefficient of coincidence.
