I am not really sure where your argument is going.

Drosophila melanogaster

... that the sequence lengths for different species are different, what should I do with them? Is there some other genes I can use for my purpose(phylogeny study) that the problem of different sequence lengths can be avoided? Thanks a lot for any suggestion in advance.
