what is ratios of phenotype and genotype in dihybrid cross?

$\huge\pink{\boxed{\green{\mathtt{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{ANSWER}}}}}}}}}$

That is, we expect a characteristic 1:2:1:2:4:2:1:2:1 ratio of the nine possible genotypes. These nine genotypes can be grouped into four phenotypes, for example 1 YYRR + 2 YYRr + 2 YyRR + 4 YyRr = 9Y-R- round, yellow peas. The ratio of these phenotypes is of course 9:3:3:1.

Answer 2

Phenotypic ratio of dihybrid cross is_9:3:3:1

Genotypic ratio of dihybrid cross is_1:2:2:4:1:2:1:1:2:1
