How Mendel set up his pea experiments MCQs with solutions
10 of the 13 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.
The cross used to reveal the genotype of an individual showing a dominant phenotype:
- A. test cross
- B. back cross only
- C. dihybrid cross
- D. selfing only
Why was garden pea especially suitable for Mendel's inheritance experiments?
- A. Clear contrasting traits and controllable pollination
- B. It reproduced only asexually
- C. It had no visible variation
- D. Its generation time was extremely long
The law stating that the two alleles of a gene separate during gamete formation:
- A. law of segregation
- B. law of independent assortment
- C. Hardy-Weinberg principle
- D. law of dominance
Why did Mendel use true-breeding parental lines in his crosses?
- A. They prevented meiosis
- B. They always produced heterozygous offspring
- C. They produced stable trait forms across generations before crossing
- D. They ensured every offspring was genetically identical after the cross
Why was garden pea particularly useful for Mendel's inheritance experiments?
- A. It had clear contrasting traits and allowed controlled self- and cross-pollination
- B. It reproduced only asexually
- C. It had no visible variation
- D. Its generations required decades
Mendel first established true-breeding lines before crossing them mainly so that
- A. parental traits were genetically consistent across generations
- B. all offspring would be sterile
- C. cross-pollination became impossible
- D. every trait would blend
To perform a controlled cross using a bisexual pea flower as the female parent, Mendel would remove the anthers before they released pollen. This procedure is called
- A. emasculation
- B. selfing
- C. grafting
- D. scarification
After emasculation, covering the flower with a bag primarily prevents
- A. contamination by unwanted pollen
- B. seed germination
- C. meiosis in the ovule
- D. formation of the stigma
Why did Mendel study one pair of contrasting traits at a time in monohybrid crosses?
- A. It allowed the inheritance pattern for a single character to be followed clearly
- B. It ensured no meiosis occurred
- C. It prevented all segregation
- D. It made every F1 plant recessive
Mendel crosses true-breeding tall and dwarf pea plants and observes all tall F1 plants. What feature of his experimental design makes the F1 result interpretable?
- A. The parents were true-breeding for contrasting forms of the same character
- B. The parents were genetically unknown
- C. The flowers were allowed uncontrolled pollination
- D. Only one F1 seed was examined
Common mistakes in How Mendel set up his pea experiments
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Assumes observed ratios are exact in every small family.
- Omits pollination control or known parental lines.
- Blames biological laws rather than loss of experimental control.
