The most probable genotype of each parent is (B) Gg × Gg.
The allele responsible for gray seed color in peas can be denoted by the letter G since it is dominant, while the allele linked with white color can be denoted by the letter g (recessive).
Now, on carrying out a self-cross between plants having gray seeds, 302 gray-seeded plants and 98 white-seeded plants were created.
Since both kinds of offspring (having gray colored seeds as well as white colored seeds) were produced, thus the parent plants must contain a copy of each allele in their genotype i.e. Gg.
