Three genes were involved in a three point test cross in fruit fly. The gene order is X - Y - Z, where the distance between X - Y is 10cm and the distance between X - Z is 25cm. If the coefficient of coincidence is 0.88, then the percentage of double recombinants obtained in this cross will be (approx value)
