For a Particular Plant, Red Flowers (A) Are Dominant Over

Essay

For a particular plant, red flowers (A) are dominant over yellow flowers (a). An initial cross was made between a plant that was correct-breeding for red flowers and another plant true-breeding for yellow flowers. F₁ progeny, all having red flowers, were allowed to self- pollinate and form seeds, which were then planted to generate F₂ progeny. Pollen from all the resulting F₂ plants was pooled and used to fertilize true-breeding yellow plants. What proportion of the progeny resulting from this cross would be expected to have yellow flowers?
