Now for the tomato. I have grown this for 3 years and every year it's the same results. Here are photos to show of my findings.
Seeds saved result in albino, yellow-green, and green seedlings. First true leaves show the light or dark green color. Albino die, but the other two grow great. One time I got a weird seedling with 3 leaves that were half albino and one red leaf, it lived about a week then died. In my photos you'll see albino seedling with others of normal color, and seedlings with true leaves, ones to left and right are light green, and the one in middle is normal green (S plant marker photo). You can see a photo of two mature plants, light green next to dark green, these are from seeds collected in the same tomato and are siblings. The difference is quite clear, especially close up of the light leaves! Flowers and fruit are normal looking and plentiful.
