63. In two different pregnancies with monozygotic twins, doctors detected only one amnion in one pregnancy and two in the other. Which is true?

		Twins sharing a single amnion separated earlier than twins with two amnions
		The number of chorions, NOT amnions is relevant for separation time
		Twins with a single amnion separated later than twins with two amnions
		It’s hard to distinguish between monozygotic twins with one amnion and dizygotic twins
