How many types of gametes may be produced by genotype $D/d : E/e : F/f$?

To determine the different types of gametes produced by a pea plant with the genotype $AaBb$,with which genotype should it be crossed?

In Mendel's dihybrid cross experiment,what is the phenotypic ratio of the progeny obtained from a test cross of the $F_1$ generation?

In a dihybrid cross between a pure tall pea plant with green pods and a dwarf pea plant with yellow pods,how many dwarf plants with yellow pods will be produced in the $F_2$ generation out of $16$ offspring?

In $F_2$ generation,a phenotypic ratio of $1:1:1:1$ exhibits

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