From the greek 'on the same string', it is used in genetics
to refer to the phenomenon that gene
s in one organism
can be in the same order as those in another. For example, if the genes are A, B and C and they are in the order ABC on the genome
s they might also be ABC in the mouse
Why is this useful? Well if you know the immediate neighbours of a gene in the mouse, you can guess that they will be the same in a human. So what, you ask? My, you are inquisitive today. This means information from a model organism can be transferred to tell you about human disease.
