The plants that were used in the experiment had to be true breeding for a trait. What does “true breeding” mean? a. The parents will produce offspring that will carry the same phenotype. b. The offspring will have the same genotype for that trait as that of the parents. c. Both a and b d. None of the above 2. What was evident in the first generation of pea plants in Mendel’s experiment? a. They produced round seeds. b. They produced wrinkled seeds. c. Some of them produced round seeds whereas others produced wrinkled seeds. d. They produced no seeds at all. 3. What did Mendel observe in the offspring of the first generation of pea plants? a. A ratio of 3:1, meaning 3 wrinkled seeds for every 1 round seed b. A ratio of 3:1, meaning 3 round seeds for every 1 wrinkled seed c. A ratio of 2:2, meaning 2 wrinkled seeds for every 2 round seeds d. A ratio of 4:0, meaning all produced round seeds 4. Which of these statements correctly depict Mendel’s law of dominance? a. The recessive allele will mask the effect of the dominant allele. b. The recessive trait will appear more frequently than the dominant trait. c. In a pair of alleles, one of them will be expressed over the other. It is described as “dominant”. d. The dominant allele will be expressed only if the recessive allele is absent. 5. Which of the following statements is not true? a. Mendel's experiment on pea plants showed that round seeds, being more frequent than wrinkled seeds, were the dominant trait. b. In Mendel's experiment, the dominant allele masked the effect of the recessive allele. c. Genetic information is passed on from offspring to parents. d. In Mendel's experiment, "wrinkled seed" is a recessive trait. Send Your Results (Optional) Your Name To Email Time is Up!
