I'd think, not. o_O; You'd just get a clone of the standard african violet, if you cut the top off and root it.

1. Practically none. You will have a clone of your plain one.

2. To my understanding the chimera mutation should come out of bicolor/multicolor violet - fantasy, or with a different colored edge, may be thumbprint. The colors were there - they just got organized differently. I imagine - that bicolor petals are someway related to the green tissue that carries cells responsible for let's say pink and blue specs on the petal.

You put your fantasy leaf down - new growth points appear - and one of them is a miniscule bud with "blue' related green cell in a middle surrounded wih pink carrying green cells. The plantlet grows - and the core of the stem carries these "blue" cells, and the outside tissue - "pink" cells. The flowers will be pink with blue stripe in the middle. If you cut the stem of the chimera - you can actually see the difference between center and outside. This pattern repeats in suckers - that's how chimeras are propagated.
Usually it is bicolor AV that sports into solid color, not reverse.

The chimeras are mostly happen at the nurseries when a lot of leaves are put down for plantlets. It is quite often when the babies do not repeat mother plant, usually they come up solids instead of mlticolors - but sometimes AV gods smile at you and the chimera shows up.

I ihave heard that chimeras are more prevalent when you put down a section of a leaf. I am going to try it by cutting a leaf in half and putting the top have in my mix to see if it happens. It might be an interesting experiment.

I mean the suckers from a standart violet which is a pure color as it is in wild? Do the suckers from a pure blue violet go to bicolor chimera formation by genetic mutation or etc?

Chimera mutations aren't something you can force...
They either happen (rarely) or don't (usually).

I actually saw the species saintpaulia converted to a chimera with a stripe in a middle of a petal. Not a very sharp contrast between light and dark blue. So Koray - it can happen. But the chance is really very very low.

So - better to use Fred's recipe - cut the leaves in slices. To increase the probability = start hundreds of them. That's why most of the chimeras come from commercial growers - they start lots of them.

Thank you irina; this is the answer what i was looking for.
