A radish is a root vegetable that produces flowers that 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-flowered, long radishes 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

In this scenario, flower color exhibits incomplete dominance, where the heterozygous condition results in a blend of the two parental phenotypes (red and white produce purple offspring). For the shape of the radish, long is dominant over oval. Therefore, crossing true-breeding red-flowered, long radishes with true-breeding white, oval radishes would result in F1 offspring that are all purple-flowered and long, as they inherit one allele for each trait from each parent.
