Selfing is the process of fertilisation with polar or male gametes of the same individual. AABbCC will produce two type of gametes ABC and AbC. Thus, in F2 generation three genotypes will be obtained. These are AABBCC, AABbCC and AAbbCC in the ratio of 1:2:1. Phenotypically AABBCC and AABbCC are same. So the phenotypic ratio in F2 generation will be 3: 1 .

Genotypic Ratio in F2 Generation
To determine the genotypic ratio in the F2 generation, we first need to understand the genetic makeup of the parent plant in the F1 generation, which has the genotype "AABbCC".
Parental Genotype in F1 Generation
- The genotype "AABbCC" indicates that the plant is heterozygous for gene A, homozygous for gene B, and homozygous for gene C.
Genetic Cross in F1 Generation
- When a plant of F1 generation with genotype "AABbCC" undergoes selfing, the gametes produced will be "ABC" and "ABC" due to the law of segregation.
Genotypic Ratio in F2 Generation
- In the F2 generation, the possible genotypes from the cross of "ABC" and "ABC" gametes are AABBCC, AABBCc, AABbCC, AABbCc, AaBBCC, AaBBCc, AaBbCC, AaBbCc, aaBBCC, aaBBCc, aaBbCC, and aaBbCc.
- The genotypic ratio in the F2 generation will follow a 3:1 ratio due to the random assortment of alleles during gamete formation.
- Therefore, the correct answer is option 'A', which represents a 3:1 genotypic ratio in the F2 generation.
In conclusion, understanding the genetic makeup of the parent plant in the F1 generation and the principles of genetic inheritance helps in predicting the genotypic ratios in subsequent generations.
