The correct answer is: Rryy, RRyy
In Mendelian dihybrid cross when heterozygous round yellow seeded plants are self-crossed, round green seeded offsprings are represented by RRyy, Rryy genotypes. This is illustrated as given below.


 
  RY Ry rY ry
 RY  RRYY  RRYy  RrYY  RrYy
 Ry  RRYy  RRyy  RrYy  Rryy
 rY  RrYY  RrYy  rrYY  rrYy
