And a Pic Of The Inside

Squash are very promiscuos, especially C. pepo. That looks like a zucchini cross with a yellow squash. With the warts probably a yellow crookneck, but it could be crosses with any C.pepo you grew last year.

If you planted hybrid Zucchini last year and seeds germinate, you can't expect them to be of the same kind - they hybrids, that means the do not inherit parents characteristics. Instead they have characteristics of one of their grandparent... If you add here open pollination between different hybrids... It is pretty much hybrid mess)

Yep pretty much

The flash made the Yellower brighter looking
It actually has more Green to it than what shows in the pic

The new ones that are growing look the same

What Would The Chance Of It Being True To Seed???

I'm guessing from what I had growing
These two would be the most likely candidates

And This Be The Other

I'd guess the Vegas odds on "true from seed" would be pretty high. Something in the neighborhood of 30:1. But how does it taste? Worth trying?
