False.

In a dihybrid cross, the expected ratio of genotypes is 1:2:1:2:4:2:1:2:1.
In this example the ratio is 1:2:2:4:1:2:1:1:1. So, this ratio is false. It is expected 1YYRR : 2YYRr : 1Yyrr : 2YyRr : 4YYrr : 2YyRR : 1yyRR : 2yyRr : 1yyrr.

Answer:

In considering the cross YyRr x YyRr, the genotype ratio is YYRR:2YYRr:2Yyrr:4YyRr:YYrr:2YyRR:yyRR:yyRr:yyrr.
