We can avoid this problem by slightly changing the typing rules to disallow such unnecessary duplications.
On the other hand, there are some duplications that seem unjustified.
There are deliberate duplications so that subjects dealt with are fairly complete in themselves.
We counted new repeats as duplications of the adjacent sequence only if the full insertion was duplicated.
Several gene duplications and losses seem necessary to explain these results.
In meiosis, duplications were always accompanied by an additional mutation event which was either an insertion of repeats from the other allele or a deletion.
