More true breeding white flowered plants.
If the gene combination for white is WW and is dominant
a cross of WW x WW would result in 100% WW (white flowered plants)
A true breeding pea plant means that when it self-pollinates, it produces offspring with the same trait as the parent plant. This indicates that the plant is homozygous for that particular trait and will consistently pass it on to its offspring.
You cross a pure-breeding plant with red flowers and a pure-breeding plant with white flowers. All the offspring have red and white speckled flowers. What type of allele relationship does this show?
corn is a flowering monocotyledonous plant

The correct term is "true-breeding". What that means is that if he takes his two pea plants with white flowers and breeds them together, he will always get a pea plant with white flowers. Something that is true-breeding for a particular trait is homozygous, i.e. if the allele for red flowers is R and the allele for white flowers is w, then a true-breeding white flowering plant is ww, and true-breeding red flowering plant is RR. If you cross-breed a true-breeding red flowering with a true-breeding white flowering plant, you would get 1/4 of the offspring as true-breeding red flowers, 1/4 of the off-spring as true-breeding white flowers, and 1/2 the offspring as heterozygous (not true-breeding) red flowers - Rw. If you don't start with true-breeding plants - say you start with Rw and ww (a red and a white plant) you get 1/2 the offspring heterozygous red, and 1/2 true-breeding white. Thus if you didn't know anymore, you would assume that half the time when you breed a red and a white plant, you would get a red plant, and half the time a white, which is incorrect. Furthermore, if you conducted the experiment again, say with RR and Rw, you would get a different result (in this case, all red). By starting with plants that are true-breeding, you ensure that you get the same results that properly show how the traits are passed on.
answer: true breeding plant
a true breeding plant always produces offspring with the same trait as the parent(s).
