Answer: If your yellow tomatoes were the old-fashioned heirloom type (sometimes called "open-pollinated"), you can save the seeds and expect them to produce plants with similar fruits. The newer hybrids won't always come true, even though tomatoes are self-pollinating. If you avoid hybrid varieties you'll be able to grow the same tomato from seed saved from each plant next year, even if different varieties were grown close together.
