Which traits did Mendel consider for his dihybrid cross experiment?

What is the expected percentage of $F_2$ progeny with yellow and inflated pod in a dihybrid cross experiment involving pea plants with green-coloured,inflated pods and yellow-coloured,constricted pods (in $\%$)?

In an experiment on pea plant,pure plants with yellow round seeds $(YYRR)$ were crossed with plants producing green wrinkled seeds $(yyrr)$. What will be the phenotypic ratio of $F_1$ progeny?

$A$ plant with the genotype $AABbCcDD$ is self-pollinated. Assuming independent assortment of the four genes,what will be the proportion of the $AAbbccDD$ genotype in the progeny?

In Mendel's experiments with garden pea,round seed shape $(RR)$ was dominant over wrinkled seeds $(rr),$ and yellow cotyledon $(YY)$ was dominant over green cotyledon $(yy).$ What are the expected phenotypes in the $F_{2}$-generation of the cross $RRYY \times rryy$?

In the cross $AABb \times aaBb$,the ratio of progeny $AaBB : AaBb : Aabb : aabb$ is:
