What is the name of a north American plant with white flowers?
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?
If all the offspring of a cross between a red flowered plant and a white flowered plant have pink flowers this means that the allele for red flowers is what to the allele for white flowers?
Is a plant with purple flowers was crossed with a plan with white flowers what is the probability that the offspring will have purple flowers white flowers or pink flowers?
Depends on your meaning of multi-colored. If you mean that each flower has several colors, but the flowers are identical, that is THAT species of rose. If you mean different colored flowers on the same plant (white, red, pink, yellow) those are the results of a plant graft- A white rose plant is grafted onto a red rose. Only the roses on the white branch will be white.
