If a pea plant is represented by $Rr$,what type of information is obtained?

$A$ cross was made between a pure tall and a pure dwarf pea plant to produce progeny. The progeny was self-pollinated. Find the ratio of the resulting true-breeding tall and dwarf plants.

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?

What is the phenotypic ratio of a single pair of contrasting traits in the $F_2$ generation of a dihybrid cross?

An $F_1$ plant has the genotype $AABbCC$. What is the phenotypic ratio of the $F_2$ generation after selfing this plant?

Self-pollination between $Tt$ and $Tt$ plants results in a genotype ratio of:
