I have squash that is both green and yellow, and it is next to cucumbers. Did they
Answer: Probably not.
Quick take: Only plants within the same species can cross-pollinate one another. Summer squash
(Cucurbita pepo) and cucumbers (Cucumis sativus) are not in the same genus or species so cannot cross-pollinate. Further, if cross-pollination
happens you would see the result of the crossing not on the fruit this year but would
see it in the seed produced inside the fruit. The seed would contain the genes of
both parents. That seed if planted and grown would produce fruit with characteristics
of both parents. If you used new seed purchased this year and are seeing abnormal
coloring on the fruit, this disorder is most likely caused by a virus or disease.
Cross-pollination is only possible within the same species. (With scientific names
the first name is the genus and the second is the species i.e. Genus species)
Virus infection on cucurbits often results in bumps and changes in color that can
be confused for cross-pollination issues as seen in the picture below.
