The chances are slim.
There are 3 processes which will cause the children to look different:
- Independent assortment - the random lining up of bivalents along the equatorial plane during meiosis.
- Synapsis, the exchange of sections of DNA between homologous chromosomes during meiosis producing 4 genetically unique daughter cells
- Random gamete fusion - the exact egg and exact sperm that meet during fertilisation are unpredictable - each combination would give a genetically different offspring.
The above conditions would have to match exactly in both sets to produce near identical offspring.

No. But they would probably look more like siblings than the cousins which they are.
Because of the way in which chromosomes separate to produce eggs and sperm, the genes which go into each one are essentially random.
Each one has half the DNA of the parent, but it's not like it is half A or half B. Since there are around 20,000 genes that make you what you are and each parent has two copies of each gene which might be different, the chance of any particular sperm or egg of being the same as the one next to it is somewhere in the neighborhood of one in so many billions that it's hard to even describe it.
In other words, a child from two sets of twins will look about as alike as brothers and sisters would - they'll only be identical if all the brothers and sisters are identical too!

Each person has 23 maternal and paternal chromosomes (46 total). When meiosis occurs each egg or sperm gets one chromosome from each pair of chromosomes. Whether it is one of the paternal or maternal chromosomes is random. So there are a total of 529 possible combinations. Actually it's more, because there's switching of genes between chromosomes during meiosis as well.
So the answer is the odds of both couples having an identical child are less than 1/529 or so low as to be practically negligable.

Your question is also like: would the children of the same couple be all the same? By experience we all know that with the exception of identical twins, children of the same parents can vary. Each child is an independent event. The previous answerer is right.

That's a really interesting question. It just depends on the way the chromosomes of the two parents combine- and since there are infinite ways and many many hidden genes that are not visible in individuals, the kids could look very different or very similar.

No, some would look more like one parent than the other and while there is a greater likelyhood of having more twins, the genetics of the grandparents and recessive genes comes in to make considerable differences (as in hair color, eye color, etc.) possible.

your toddlers might look alike and marry same twins and so on and so on and until there have been in basic terms twins in the international and in some years there could be in basic terms 2 styles of faces in the international. i'm hoping you're the two very beautiful.

There is a slim chance that they will look the same since the gene combines differently in different environment.
Most likely, they will not look the same.

They would look similar to each other, but no more so than siblings of a single pair of parents do.
