If a plant heterozygous for tallness is selfed, f2 feneration has both tall and dwarf plants. this proves the principle of__________________?
Correct answer: C. Segregation
- A. Dominance
- B. Independent assortment
- C. Segregation
- D. Incomplete dominance
Explanation
Selfing a heterozygous tall plant (Tt × Tt) separates the two alleles and produces tt dwarf offspring along with tall plants. This visible reappearance of the recessive trait demonstrates Mendel’s law of segregation.
