The ova all come from the germline so IMHO it's overwhelmingly likely they would have the same DNA but it's not exactly guaranteed: it depends if her ovaries are chimeric.
It’s more complicated. The germline cells are “chosen” in a very early stage of the embryo, and later they migrate to the ovary/testes. So perhaps the tissue of the ovaries are from one chimera-twin and the germline cells and the eggs from the other one. (Perhaps each embryo selected the germline cells, and both group moved to the ovary later??)
