What is your logic here?  Certainly you will lose individual genes as time 
goes by, but if you are dealing with horses where the Arab portion is a 
significantly high percentage and they are regularly bred back to each other, 
you will randomly lose Arab genes AND genes of the other (in this case 
Tarpan) foundation stock.  The modern breeds of the world DO NOT resemble 
Tarpans very closely--in fact, for the most part, they share more traits with 
the Arabs.  That would be suggestive of the fact that more Tarpan ancestry 
has "washed out" over time than the Arab portion.  Color is an 
example--Tarpans tended to be (as near as researchers can tell) duns, 
buckskins, etc.--and only a few modern breeds even HAVE individuals of these 
colors.  The very absence or rarity of the Tarpan influence in color alone is 
genetic evidence that the Arabian influence still remains.
