Question:
A gene in snapdragons determines whether the flowers will be red (genotype RR), white (genotype rr), or pink (genotype Rr). A garden club has planted a garden of snapdragon plants. The garden contains 9 red, 42 pink, and 49 white plants. A family of rabbits selectively eats all of the white plants before the plants can reproduce. The surviving plants from the first generation are allowed to mate randomly and produce the second generation of offspring.
1. Using Punnett squares, predict the flower colors that you would expect to see in the second generation.
2. If the rabbits continue to eat only the white plants, predict what would happen to the snapdragons over the course of succeeding generations.
