In tomato plants, normal growth is a dominant trait (B), dwarfism is a recessive trait (b) Determine the genotype

In tomato plants, normal growth is a dominant trait (B), dwarfism is a recessive trait (b) Determine the genotype and phenotype of parents and offspring, if the offspring is split according to these traits in the ratio 1) 1: 1; 2) 3: 1

1) Since a 1: 1 split is observed in the offspring, this corresponds to Mendel’s law of uniformity in monohybrid crossing, in which one parent is heterozygous (Bb) and the other is homozygous (bb). In this case, the phenotypes of the parents are a plant with normal growth (Bb) and a plant with dwarfism (bb), the phenotypes and genotypes of the offspring are the same as those of the parents.
2) Since a 3: 1 splitting is observed in the offspring, this corresponds to Mendel’s law of splitting in a monohybrid crossing, in which both parents are heterozygotes (Bb) with normal growth in the phenotype. Then the offspring will have the following genotypes – BB (normal growth), 2 Bb (normal growth) and bb (dwarfism).
