In a plant species, allele A (dominant) gives purple flowers, allele a (recessive) gives white flowers, and heterozygotes (Aa) show pink flowers (incomplete dominance). A cross is made between a pink‑flowered plant (Aa) and a white‑flowered plant (aa). A seedling is then selected at random from the F1 generation and allowed to self‑fertilise. What is the probability that a randomly chosen offspring of this self‑fertilised seedling will have white flowers? Express your answer as a fraction in lowest terms.
