2. There was no significant difference in the asymmetry and non-congruence between monozygotic and dizygotic twins.

3. Acardia is a severe, complex malformation of monozygotic twinning, but beyond clinical case series, very few epidemiologic data are available

4. Gringas and Chen (2001) describe a number of mechanisms which can lead to differences between monozygotic twins, the most relevant here being chorionicity and amniocity.

5. Amblyope 1 point 2 points 3 points 8 years ago I believe it depends on whether or not the egg split (monozygotic) or two eggs were fertilized (dizygotic)
