Answer:
Option D
1 YYRR: 2 YYRr: 2 Yyrr: 4 YyRr : 1 YYrr : 2 YyRR : 1 yyRR : 2 yyRr: 1 yyrr
Explanation:
The genotype of the cross between dihybrid cross will be as follows
YR
Yr
yR
yr
So the punnet square for this cross will be as follows -
 YR      Yr      yR      yr
YR YYRR YYRr YyRR YrRr
Yr YYRr YYrr     YyRr Yyrr
yR YyRR YyRr yyRR yyRr
yr YyRr Yyrr     yyRr yyrr
The genotypic ratio is as follows -
1 YYRR: 2 YYRr: 2 Yyrr: 4 YyRr : 1 YYrr : 2 YyRR : 1 yyRR : 2 yyRr: 1 yyrr
Hence,option D is the correct answer
