Hello Qu,

The "RefSeq Genes" track on the chimpanzee assembly contains both human 
and chimp records, because there are relatively few chimp RefSeq genes 
(currently < 750).  The chimp assembly has the only RefSeq Genes track 
that is treated as a special case in this way (at the time of this 
email, anyway!).

This difference is documented on the track description page, which you 
can get to by clicking on blue title "RefSeq" above the track pulldown, 
or by clicking on the blue/gray bar to the left of the track in the main 
display.

To get only the chimp RefSeq genes from the Table Browser, select the 
refGene table just as you describe, and then hit "filter: create".  On 
the next page, choose the panTro2.gbCdnaInfo table and hit the "allow 
filtering using fields in selected tables" button.  Scroll down -- there 
should now be even more tables to choose from.  Select the 
"panTro2.organism" table and hit the "allow filtering" button again.

Now, under "panTro2.organism based filters", enter "Pan troglodytes" in 
quotes so that the filter consists of:

name does match "Pan troglodytes"

and hit submit.  Now you should be back on the main Table Browser page, 
where you can hit "get output" to get your results.

I hope this helps you get the information you need.  If you have further 
questions, please feel free to contact us again at [email protected].
