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

If $3^n$ is the theoretical number of different genotypes (where $n$ is the number of heterozygous gene pairs),then the number of different genotypes produced by a pea plant with the genotype $AaBbCcDdEeFfGg$ is:

$A$ cross between one tall plant and one dwarf plant resulted in offspring having tall plants. What would be the genotype of offsprings?

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

$A$ true-breeding plant producing red flowers is crossed with a pure-breeding 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, the proportion of plants producing red and white flowers in the progeny would be:

In pea plants,hybrids between red-flowered and white-flowered strains were crossed back to a pure red-flowered strain. The progeny of this cross will have:
