Is it possible to cross pollinate a zucchini and a regular pumpkin? And what does it look like?

Cross pollination can be seen in the squashes and pumpkins. Summer squash, pumpkins, gourds, and some types of winter squash belong to the same plant species Cucurbita pepo. All species members may cross with one another. Thus, an acorn squash will cross pollinate with a zucchini or a miniature gourd.Aug 23, 1996
