what does the branch length computed with APE neighbor joining tree represent ?

Hi,

I have build a tree using the dist.alignment() function in seqinr and the nj in APE for amino acids

What does the branch length represent? Is it a genetic distance or number of substitutions of amino acids or something else?

Regards
