Rene, I would disagree that pollination between different types of citrus produces any different fruit. Different seeds, sure. We have a number of citrus varieties planted near each other in our orchard. Each produces their expected, distinctive fruit, the Washington Navel, Cara Cara (red flesh Washington) and Valencia for oranges. The nearby grapefruits produce either Ruby (red/orange pulp) or Rio Blanco (white pulp) also as expected. Perhaps you have a Ruby grapefruit?
