Hand Pollinating Zucchini

(Frequently Asked?) Questions about hand pollination:

1. Can pollen be saved on a q-tip or just save the anthers in a ziploc bag?
2. If so, does it have to stay moist, and how long will it last?
3. How long after the male flowers have re-sealed and wilted can I tear them open and still use the pollen?
4. How long after female flowers have re-sealed and wilted can I tear them open and still pollinate them?
5. Can I use pollen from the same plant, or do I need to use both plants to pollinate the other?

Thanks!

Mostly good stuff, but many photos missing and video, but I get the gist. Thanks a lot.
