In snapdragon plants, the gene for red petals (R) is incompletely dominant to the gene for white petals (r). Individuals that are heterozygous (Rr) have pink petals. A plant with pink petals is crossed with a plant with white petals.

What is the chance that the offspring will have red petals?

Rr x rr = Rr, Rr, rr and rr

chances of having red petals is 0% as pink petals is 50% and white petals is also 50%
