I'm a Biology & Chemistry teacher & tutor. And the
answer is no. Even without going into technicalities of genetics,
common sense will tell you the answer (so this is a good IQ
question, not necessarily only for Biology students).
How so? Just think about any couple. Does their first child look
like their second child? So even if you've a carbon copy of this
couple... you get the idea.
In terms of genetics then, a summary is this :
Johnny and Tommy are identical twins, they have identical
genes.
Jane and Mary are identical twins, they have identical genes.
If either couple (Johnny and Jane; Mary and Tommy) have identical
twin children, then the children will look the same, *within*, not
*across* the same immediate couple family.
Comparing across the two couples, you will find that, identical
twin children or not, couple A's children cannot look the same as
couple B's children, because of the same reason why the first child
never looks the same as the second child :
There are genetic/biological factors occurring during the process
of meiosis and/or sexual reproduction that cause variation from
parent to offspring, and/or between one population and another (of
the same species). These factors (by no means exhaustive, and in
random order) are :
1. Law of Independent Assortment (Meosis)
2. Law of Segregation (Meiosis)
3. Genetic Recombination due to Crossing over at Chiasmata
4. DNA Replication Errors or Point Mutations
5. Euploidy and/or Aneuploidy
6. Gene Flow
7. Genetic Drift
8. Natural vs Artificial Selection
9. Convergent Evolution vs Divergent Evolution vs Adapative
Radiation
10. Evolution & Speciation
