about 1-4%.
Animal twins
Twins are common in many animal species, such as cats, sheep, ferrets and deer. The incidence of twinning among cattle is about 1-4%, and research is under way to improve the odds of twinning, which can be more profitable for the breeder if complications can be sidestepped or managed. The nine-banded armadillo (Dasypus novemcinctus) has identical twins (usually four babies) as its regular reproduction and not as exceptional cases.

Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth.
Identical twins happen by chance only; 4 per 1000 births or 0.004 probability. Fraternal twin probability is increased only if it is on the mother's side; so this does you affect your circumstance (from what you have stated). The chance of fraternal twins is 1 in 60 or 0.017. So, your probability of identical twins is 0.004 and fraternal twins is 0.017 (BTW, I have triplets).
