If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.

With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.

With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.

With a heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.

The answer is B. Conduct a test cross with a purebred recessive plant.
