In radishes, the shape may be long, round, or oval. Crosses between long and oval resulted in 50% long and 50% oval offspring. Crosses between round and oval resulted in 50% round and 50% oval offspring. What percentage of radishes will be long, round, and oval (in that order) if long radishes are crossed with round radishes? Answer: % long, % round, % oval.
Homework Answers
It is an example of incomplete dominance. That's why cross between long radishes and round radishes will result in 100% oval radishes. See the detailed explanation in the attachments.

In radishes, one gene governs fruit shape, with the phenotypes long, round, or oval, and another independently assorting gene governs color, either red, white, or purple. You cross a long, white variety with a round, red one and obtain an oval, purple F1.
