The gene that controls the color in radishes exhibits incomplete dominance. A purebred red(RR) radish crossed with a purebred white raddish(rr) will produce a purple raddish(Rr). What are the possible genotype and phenotypes of the offspring if you will cross a purple radish and a red radish? 1. What is the phenotypic ratio of the F1 cross?
2. What is the genotypic ratio of the F1 cross?
3. if you will cross a purple radish with another purple radish, what will be the probability that the offspring will be red radish?

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.
