A horticulturalist wants to produce geraniums with specific characteristics.

She knows that the trait of red flowers is governed by the allele R (RR and Rr) and the trait of white flowers is governed by the allele r(rr) .

The horticulturalist crosses two geraniums from the F1 generation.

Look at the Punnett square to see this cross.
R r
R RR Rr
r Rr rr
