Radish flowers may be red, purple or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant trait. If true-breeding red long radishes are crossed with true-breeding white oval radishes, the F1 will be expected to exhibit which of the following phenotypes?

Question

Quizplus · Accepted Answer

When a red-flowered long radish is crossed with a white-flowered oval radish, the F1 offspring will inherit the dominant long trait from the red parent, resulting in long radishes. As for the flower color, since the cross is between a red-flowered plant and a white-flowered plant, the offspring will be all purple because red is dominant over white. Therefore, the F1 will exhibit purple and long phenotypes.
