If the spherical seed character is dominant and tall trait is incompletely dominant, what would the phenotypes of the progeny be from crossing a SStt plant with an ssTT plant?

In this cross between a plant with the genotype SStt (homozygous dominant for spherical seeds and homozygous recessive for height) and a plant with the genotype ssTT (homozygous recessive for seed shape and homozygous dominant for height), the progeny will inherit one allele from each parent for both traits.

For the seed shape, all progeny will inherit one S allele from the SStt parent and one s allele from the ssTT parent. Since spherical seed shape is dominant, all the offspring will display the spherical phenotype.

For the height trait, the offspring will inherit one t allele from the SStt parent (homozygous recessive for height) and one T allele from the ssTT parent (homozygous dominant for height). This results in a heterozygous genotype (Tt) for height, and due to incomplete dominance, the height phenotype will be intermediate between tall (dominant) and short (recessive).

Consequently, the progeny will be uniformly spherical-seeded and exhibit an intermediate height, aligning with the option that describes all progeny as spherical-seeded and of intermediate height. This combination of traits results from the principles of dominance and incomplete
