Riddle me this!

I purchased three red habaneros from a supermarket and saved their seeds. Subsequently, I planted all those seeds in a single pot, until they reached a height of 4 inch. Then, I transplanted the five strongest specimens into their permanent growing spot.

Strangely, all five plants produced yellow fruits, quite distinct in shape from the initially round supermarket habaneros; mine tend to be pointy. Notably, the color of my habaneros also varies significantly. The first harvest yielded predominantly round and orange fruits (3rd picture), but the second batch was mostly pointy and bright yellow, with some appearing orange or even a mix of orange and yellow (4th picture) (I usually wait five days after they’ve fully turned to ensure they’re ripe).

This shift in color and shape is typical of cross-pollination, as seen in commercial greenhouses. However, since my five plants likely originated from different fruits due to the mixed seeds, and there’s no noticeable wild variation among my plants (which would be common in F1 or F2 seeds), I’m genuinely curious about what might be causing such consistent but significant variation from the original ‘mother fruit.’

Could factors like soil or temperature influence the color?
