No, they can be different. Your blood group can also be different to both of your parents.

No -BUT -I made a fundamental error (sorry off topic) when we were watching a prog about how your DNA can tell where you originated from.
I turned to my sis and said -you get yours done and i'll get mine done -just for a laugh.

She just looked at me in astonishment and my poor mum said "I can assure you you both have the same DNA".

What a faux pas -but we had a laugh and I would still like to get ot doen -apparently its only �25 -might go and google just now in fact -lol
