Calculation of Phenotypic and Genotypic Ratios

Q. A plant of $F_1$-generation has genotype "AABbCC". On selfing of this plant, what is the phenotypic ratio in $F_2$-generation:

1. 3: 1
2. 1: 1
3. 9 : 3 : 3: 1
4. 27: 9: 9: 9 : 3 : 3 : 3: 1

Q.

A tall violet flowered plant (TTVV) is crossed with a dwarf white flowered plant (ttvv). When the $F_1$ plants are self-pollinated, a total of 1600 $F_2$ plants are produced. How many plants of $F_2$ generation are similar to the original parents in terms of both genotype and phenotype?

1. 900

2. 300

3. 100

4. 200

Q. A tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plant. When the F1 plants were selfed the resulting genotypes were in the ratio of:

1. 1 : 2 : 1 :: Tall homozygous : Tall heterozygous : Dwarf
2. 1 : 2 : 1 :: Tall heterozygous : Tall homozygous : Dwarf
3. 3 : 1 :: Tall : Dwarf
4. 3 : 1 :: Dwarf : Tall
