Worked practice questions

Mendel was the first to apply to problems in biology:

  1. Seasonal analysis
  2. Statistical analysis
  3. Structural analysis
  4. Spectral analysis
Show answer and solution

Correct answer: B. Statistical analysis

1. Mendel counted the offspring showing each trait. 2. For the first time statistical analysis and mathematical logic were applied to biology. 3. So the correct answer is statistical analysis. _Source: syllabus Biology, Ch 5 'Principles of Inheritance and Variation'_

How many true-breeding pea varieties did Mendel select?

  1. 34
  2. 44
  3. 14
  4. 24
Show answer and solution

Correct answer: C. 14

1. He needed plants that bred true for each trait. 2. Mendel selected 14 true-breeding pea varieties. 3. So the correct answer is 14. _Source: syllabus Biology, Ch 5 'Principles of Inheritance and Variation'_

Crossing a tall pea plant with a dwarf one gives an F1 that is:

  1. All dwarf
  2. All medium
  3. All mixed
  4. All tall
Show answer and solution

Correct answer: D. All tall

1. Only one of the two parental traits appears in the first generation. 2. Mendel observed that all the F1 progeny were tall. 3. So the correct answer is all tall. _Source: syllabus Biology, Ch 5 'Principles of Inheritance and Variation'_
