[ensembl-dev] fetch all within species paralogous genes

[shaohua fan]

Dear all, 

As a newbie of Ensembl compara API, I want to ask whether there is a way to fetch all the within species paralogous genes of one specified genome by using the compara API? I have searched the former emails and Ensembl website and only found the solution for the single gene in the tutorial of compara API. 

Thanks a lot!
