I am writing from the Museum of Science and Industry in Chicago.
We are developing an exhibit on genetics and I am wondering if 
anyone could verify a couple of pieces of information that I'd like to
include in the exhibit. 

As part of a genetic comparison of different species, I'd like to 
provide estimates of the number of genes and the percent 
homology with humans. I've seen estimates of the number of 
zebrafish genes at about 50,000 (from a publication in 1997) and 
wonder if this is still considered to be true or if this estimate has 

Also, wondering about a figure of 85% homology with humans 
(based on analysis of 831 genes only) and wonder if anyone can 
direct me to any additional information.  

Thank you,
Patricia Ward
