Question

When a tall homozygous plant was crossed with a short homozygous plant, the F1 offspring were all tall. No short plants were present in the F1 generation. Which principle does this situation represent

Answer 1

welcome to openstudy!!

Answer 2

the principle of dominance....

Say the genotype of plant 1 is TT(tall, homozygous) and plant 2 is tt(short, homozygous).
T is dominant over t.
Crossing the two plants, we end with genotypes that all show Tt.
Since T is dominant it will show between the two, resulting in all tall plants.

thank you
