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 alleler (fr).
The horticulturalist crosses a heterozygous geranium with a white geranium. What would be ratio of red to
white flowers that we would expect from this cross?
1 red: 3 white
3 red: 1 white
All red
1 red: 1 white
