Answer:
1/4
Explanation:
According to the given information, the dominant plant is back-crossed with a homozygous recessive parent. Therefore, the dominant plant is heterozygous for both genes.
The genotype of the tall plant with smooth seeds would be = TtSs
And the genotype of the dwarf parent with wrinkled seeds = ttss
A cross between TtSs x ttss gives heterozygous tall plants with smooth seeds (TtSs) in 1/4 ratio.
