Worked practice questions

Which of these is NOT possible for the offspring of a TT × tt cross?

  1. All TT homozygous tall
  2. All Tt heterozygous tall
  3. Genotype matches one parent and not the other
  4. Phenotype tall in 100 percent of cases
Show answer and solution

Correct answer: A. All TT homozygous tall

1. The TT parent contributes only T gametes. 2. The tt parent contributes only t gametes. 3. Every fertilisation gives a Tt zygote. 4. So every F₁ offspring is heterozygous Tt and shows the dominant tall phenotype. 5. No offspring is homozygous TT because no t-free × t-free combination is possible. 6. Hence option B (all TT homozygous tall) is impossible from this cross. _Source: syllabus Science Ch 9 'Heredity' (learncbse.in extract)_
