Answer: No, only identical twins will look identical.
Explanation:
Identical twins are also called monozygotic twins. Such twins are produced by the fertilization of one egg that splits into two. The genes present in these twins are same thus the expression of traits is also same in them and they have the same sex.
Sam and Joe and Maria and Ella are identical twins these pairs are expected to have same genotypic and phenotypic traits. They may be clones of each other. But if Sam and Maria are married and Joe and Ella are also married then their children will have some similar traits in common but their children will not be identical as they are not identical twins as their parents were.
