How can we reconcile humans having 3 million places they differ while
only having 300 genes that mice don't have? I think it's because in the
latter case they are counting gene analogs. They don't count the genes as
different solely because there is a small variation. So Venter is saying
that there are 300 genes in the human genome that have no corresponding
gene in mice.
