Identical twins' offspring are genetically related, not cousins.
Cousins who have identical twin parents have a 25% rather than a 12.5% DNA similarity. Half-siblings only share 25% of their DNA, whereas complete siblings share 50%. Because of this, even if identical twin children are officially cousins, genetically speaking they are half-siblings.
