Melani There was a program on television which mentioned that if one is lefthanded the chances are that you might be one of a mirror twin. Seeing that in the 1970' the sonar was either early stages or non existant and could therefore not be determained if it was so. Could you please shed some light on this subject. Thank you. 3/20/2008

Margie Weisband Why would half-identical twins only share 25% of their DNA while fraternal twins share 50%, since half-identifical twins share the same egg? 12/23/2006
Francesca I believe that your statement that half-identical twins share 25% of their DNA is wrong. If identical twins share 100%, and fraternal twins 50%, then half-identical would have to share 75%.
