Genetics edit

A 2006 genetic analysis conducted by Anderson L. Alves, Claudio Oliveira, Mauro Nirchio, Angel Granado, and Fausto Foresti concluded that Hypostomus goyazensis has a diploid number of 72 chromosomes. This is the same diploid number seen in its congener H. regani, although it differs from the diploid number of 68 chromosomes seen in H. ancistroides.[4]
