So does that mean those males are also male makers?

Correct. Male bananas from the clutch would also be male makers.

From the paper's abstract: ".... Furthermore, phylogenetic patterns of facultative parthenogenesis in snakes and a sex-linked color mutation in the ball python (Python regius) are best explained by boas and pythons possessing an XY sex chromosome system [6, 7]. ...."

Used to be that all snakes were believed to have ZW sex chromosomes. But banana's breeding pattern is impossible with ZW sex chromosomes. Proving the XY pattern in pythons removes the major block to accepting that banana is sex linked.

Breeding data for coral glow (AKA banana) is in a paper by Christopher S. Mallery Jr. and Maira M. Carrillo, A case study of sex-linkage in Python regius (Serpentes: Boidae), with new insights into sex determination in Henophidia. Phyllomedusa 15(1):29-42, 2016. The abstract is online (www.revistas.usp.br/phillo/article/view/117124). That page has a link to the full text in pdf format.
