if A and B are female identical twins, and C and D are male identical twins, what is the genetic relationship between a child of A and C, and a child of B and D?

In: Biology

It would be like they siblings, genetically speaking. So any DNA test would say the child of A and C and the child of B and D would have the same parents and thus be siblings.

Genetically, they’d be closer to siblings than cousin’s, but would be considered cousin’s because different parents

Any children from AC would be cousins to children from BD, however genetically the cousins would be so similar that most DNA tests would indicate that they were siblings.

Legally, they’ll be cousins. Genetically, they’ll be siblings. Well, more or less. There is always *some* genetic difference between identical twins, but discounting that, the two children have genes that came from what amounts to the same “pool” of possible genes. They’d show up as siblings on a DNA test.

If the parents were not identical twins then the children would be like half-siblings. If the parents are identical twins, then the children would be like normal siblings.
