    It sort of depends on what the father's and mother's genotypes are

    Father RR, Mother rr

    __R__R

    r|_Rr__Rr

    r|_Rr__Rr

    Father Rr, Mother rr

    __R__r

    r|_Rr__rr

    r|_Rr__rr

    Is it possible that the mother is Rr?

    Father RR, Mother Rr

    ___R__R

    R|_RR_RR

    r_|_Rr__Rr

    Father Rr, Mother Rr

    ___R___r

    R|_Rr__Rr

    r_|_Rr__rr
