Can you be identical twins with different genders?

In very rare cases, identical twins can be different sexes. These twins begin as identical male twins. Like all males, they both have XY sex chromosomes, instead of XX like all females do. Very soon after the egg splits in two, a genetic mutation causes one twin to lose its Y sex chromosome, changing it to X0.

Why are identical twins so rare?
