In pea plants, the allele that produces purple flowers (P) is dominant to the allele that produces white flowers (p), and the allele that produces tall plants (T) is dominant to the allele that produces short plants (t). Two pea plants are crossed and produce 521 offspring, and the results of this cross are shown below:


Phenotype Number of offspring
Tall with purple flowers 291
Short with purple flowers 97
Tall with white flowers 101
Short with white flowers 32


Which cross would MOST LIKELY lead to this outcome?
