If that were true then all brothers and sisters would look the same.

you are over looking the recessive genes that their DNA is hiding. I thought this was obvious

is it not technically impossible for a pair of twins, male and femal, to be classed as identical?
surely the fact that they are of opposite sexes means they are not identical?

I understand the question, my point is that you are asking whether similar parents have similar children. The answer is no, as my parents were genetically similar when the had me and my brother, but my brother and I are not identical.
If parents of more than one child don't have identical children, then disjoint parents who are genetically identical won't either.
ie. the twin parents second child won't be the same as their first, which won't be the same as their brother/sister in laws.
The dominance or recessiveness of any one particular gene has little to do with this queston, as if a gene were recessive in one parent it would be recessive in the other. Thats not to say that any one particular zygote consistently contains the same combinations.
You could rephrase the question to say that if the twin parents both played a game of tennis the score would be the same. It wouldn't.

Is everyone in this thread overlooking the fact that out DNA holds recessive and dominant genes 
There is no telling which genes be it recessive or dominat will be passed on.
Its pretty clear. Please stop the discussion.

Yes but the parents are genetically identical, therefore any dominance will be replicated. What you appear to be missing is that there's a rather big choice of haploid in any given fertilisation.

GCSE Biology teaches you the opposite? You learn that if both parents have blue eyes then the child will also due to the recessive nature of the gene for blue eyes?
If anything, the GCSE Biology answer agrees with Nismo, not disagrees.

Twin brothers - who are identical - marry twin sisters - who are identical.

that assumes they have two copies of the gene.

No you tit.
Their genetic make up did not differ in the time between my conception and that of my brother.

not exactly true. it is possible your parents to suffer mismatches (UV damage) in their DNA between your conception and your brother. it is possible that certain genes could be mutated and so get a change in certain phenotypes
