I might be wrong, but I think that you'd still get a yellow squash, and the seeds of that yellow squash would produce some mixed hybrid. When zuke and yellow squash are planted side by side in a garden I'm sure there's some cross pollination going on, and I've never seen a squash that wasn't typical to the plant it was on.Question, has anyone ever used a male zucchini flower to pollinate yellow squash? I had no male yellow squash flowers and 3 females open & ready to go. I figured I had nothing to lose. Worse case, it'd do nothing or give me some kind of hybrid fruit.
And it might not even successfully pollinate. But try it, sounds like an interesting experiment. I think James Prigioni of the Garden Channel (youtube) uses a Q-tip to transfer the pollen.
I have different 6 tomato varieties planted together in a 5'x7' bed. I might save some seeds to plant next year and see what kind of weirdness happens. LOL
