Rowan is conducting a plant experiment with pea plants. In the F1 generation of a monohybrid cross (Ss x Ss), the phenotypic ratio of tall to short plants would be:

Aria is studying genetics and learns that tallness (T) is dominant to dwarfness (t), while red (R) flower color is dominant to white (r).

What are the genotype and phenotype of the F1 individuals?
