The Figure Below Shows Three Generations in One of Mendel's

question 8

Multiple Choice

The figure below shows three generations in one of Mendel's experiments.
The data in this figure demonstrate that purple flower color is dominant in peas. Which of the following is the best rationale for this conclusion?

• A) In the F2 generation, more plants have purple flowers. In any cross, the allele that is most common in the offspring is dominant.
• B) Members of the F1 generation are heterozygous. Whatever allele is visible in a known heterozygote is considered dominant.
• C) The stronger, or in this case, darker, allele is always considered dominant.
• D) An individual that produces more offspring gives more alleles to the next generation. As a result, that allele dominates the next generation.
