Special Boys Identical Twins

Identical Twins

Identical twins are the result of one egg splitting post-fertilization, but the timing of the split determines if the twins will each have their own sacs and placentas (split on day 1-3, called di/di twins), share a placenta (split on day 4-8, called mo/di twins), share an amniotic sac and placenta (split on day 8-13, called mo/mo twins) or be conjoined (split on day 13-15) which is, of course, the most rare: only 1 in 200,000 births.
