Most of the individuals of a certain wildflower population have yellow flowers, although a few are white-flowered. Crosses have demonstrated that allele for yellow flower (Y) is dominant over the allele for white (y). If two heterozygous yellow-flowered plants are crossed, what fraction of the offspring do you expect to be white? Show your solution.
