Mystery Squash from Compost: Hybrid Cucurbit Surprises

Q: Compost volunteers produced round, ridged, light-green fruit—not yellow squash or zucchini. What are they?

Cucurbits (squash, cucumbers, gourds) cross-pollinate freely via insects. Your compost seeds had mixed parentage. The fruit you ate was normal; the seeds carry hybrid genetics. Resulting fruit won't resemble parents and may be inedible—but fun to speculate about!
