[ ________ Dros1
[ _____ Anoph1
I am wrting a paper comparing some genes in
Anopheles and Drosophila. There are cases where
Anopheles has an extra gene (in a family) compared to Drosophila--
I figure it is either gene expansion in Anoph or gene *loss*
in Drosophila. I'm going to say that when I get the bottom tree
it must be gene duplication/divergence in Anoph but when I get
the top tree it's gene loss in Drosophila. How would I say it though?
Top tree "must be gene loss in Drosophila because gene duplication
/divergence of gene 1 and 2 occurred before divergence of
Anoph and Drosophila"? Is that the proper interpretation?
Please let me know. NJ and ML tree show same tree (top).
