It would have been easier to produce true-breeding peas with the trait caused by a recessive allele because only one copy of the recessive allele is needed to exhibit the trait, whereas two copies of the dominant allele are needed. Therefore, for true-breeding individuals with the dominant allele, both parents must have the dominant allele, which is more rare in the population.
