For almost all primes split in a real quadratic field, we describe how to determine the isomorphism class  of  the  universal  ordinary  deformation  ring  of  a  2-dimensional  induced  representation  from  the  Galois group over the real field.As an application, we can write down explicitly its base change to the quadratic field and the adjoint Selmer group of the universal deformation.
