Imagine you are given two tall plants, but you do not know their genotype (see Figure 16-12). There are three possibilities—they might both be TT or both Tt or one TT and the other Tt. Imagine you cross the two plants, wait for them to produce seeds, and then plant the seeds. If all resulting plants are tall, can you then determine what the genotypes of the two parents are? If approximately half the resulting plants are tall and about half are short, can you then figure out the genotypes of the parents?
