2nd deformed tomato flower grows fruit.

Hi folks, one of this years tomato plants have again grown a defective flower like the one that grew several years ago.

So, here are a couple of photos of it, there is a normal tomato on the same plant as well.

The flower is deformed and resembles a large daisy, or a small sunflower . The fruit that has grown on the flower appears to be on a about a quarter of the flower.
Which brings a question, again, is this more common than I thought, and can you get 2 or more tomatoes growing on the same large multi flower?

I'll try and collect some seeds and see what happens with them.
