I have now scanned though the Paper, and find the explanation of
their calculation of Expected Length (which agrees with the method
I described in my previous email) in a somewhat garbled description
on page 1198 (page 10/12 of the PDF file):

  "The expected gene number lambda_i on chromosome i would be
   a sample from a Poisson distribution lambda_i = m*L_i/Sum L_i
   where m is the total number of genes detected within the
   assembled sequences and L_i is the length of chromosome i."

I agree with your earlier comment, Glen, that the paper would have
benefited from more careful scrutiny by referees/editor!

Best wishes,
Ted.
