The correct answer would be YYRR:2YYRr:2Yyrr:4YyRr:YYrr:2YyRR:yyRR:2yyRr:yyrr.
Gametes produced by each parent = YR, Yr, yR, and yr.
The cross is shown in the figure attached.
Types of genotypes observed were:
YYRR : 1/16
YYRr : 2/16
Yyrr : 2/16
YyRr : 4/16
YYrr: 1/16
YyRR : 2/16
yyRR : 1/16
yyRr : 2/16
yyrr : 1/16
I hope this helped you.
