Sweet Jumpin' Genes He Has 8 Fingers

 This picture may only show a flower bursting with a lovely lilac color, but really there is 100's of jumping genes at play forming a mutation.The color gene in this flower, purple or white (you can't assume it is one or the other), has jumped around the DNA either cutting itself from one part and going into another or duplicating, and sending the copy to another segment. With the movement of this gene a mutation forms making the flower splash with vibrant colors. At one point in previous generations of this type of flower, it may have been all purple or white.
In this lil' curly devil's genes there was a duplication because of a movement in the Zone of Polarizing Activity (ZPA).  When shifted this can cause a duplication of certain structures.  In this case it was fingers, the ZPA must have moved multiple times and created many fingers on accident. This is why this child has so many excess phalanges.
