FlytrapCare Carnivorous Plant Forums

I found one trap from small plant that looks as the cupped cultivar? Is that just genetics went wrong because all the traps are common ones.

Yup. Just a genetic misfire if it hasn't done it before. All venus flytraps will do that sort of thing occasionally.

If I cut that leaf close to rhizome for propagating it, will the new plant have all traps in the same way?

Propogating through leaf pullings creates a cloned plant. Your pulling plant will be exactly the same as the mother plant. So if the mother plant makes cuped traps frequently, then its clone will too.

If you are asking if it will produce all cups like the leaf it was pulled from, the answer is no. The same rules will apply for any leaf on the mother plant. It won't create a fully cupped plant just because it came from a cupped leaf.
