Source (rows): source protein for BLAST query
Homologs (columns): sequences in match with bitscore >= 50 and alignment > 50% of protein length
N genes column: Number of protein sequences available for the organism

Methods:

Inparanoid analysis of orthologs from winter 2005.
See Inparanoid: a comprehensive database of eukaryotic orthologs.

The counts in this table are of the number of available genes for an organism, and those which have one or more significant homologs in the other organisms. Percentages are the count of genes with any homolog (one or several) in another organism, divided by the total available genes in that organism (x 100).

You can read the homology summary table best this way. To answer the question what percent of all fruitfly genes have any homologs in C.elegans, look at the Fruitfly row, and find the Worm column. To answer the reverse, the Worm row and Fruitfly column says the percent of all worm genes that have any fruitfly homologs.

Note the asymmetry in these counts and percents. Fruitfly genome may have 5600 of its 13000 genes (43%) showing some homology to Human genes, whereas the Human genome may have 8700 of its 47000 genes (18%) showing some homology to Fruitfly genes. These include the same gene-pairs.
