The number of phenotypic recombinant offspring formed during the $F_2$ generation of a dihybrid cross is . . . . . . . (in $1/16$)

The phenotypic ratio of a dihybrid test cross performed by Mendel is ....

Types of genotype observed in a dihybrid cross are

During a dihybrid cross, in the $F_2$ generation, the ratio of individuals showing one dominant and the other recessive character will be . . . . . . of the total population. (in $/16$)

In a plant,red fruit $(R)$ is dominant over yellow fruit $(r)$ and tallness $(T)$ is dominant over shortness $(t)$. If a plant with $RRTt$ genotype is crossed with a plant that is $rrtt$,what will be the phenotypic ratio of the offspring?

What is the percentage of recessive gametes produced by $YyRr$ (in $\%$)?
