Also another fact is helpful, which indicates that some ink are water soluble and some are alcohol soluble. Different types of ink pen uses various types of inks, when this is mixed with certain solvents the components of the mixture thus obtained forms a banding pattern which is very unique to that particular. This is also called ink chromatograph.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
