No it is a Monomorphic yeast.

In monomorphic species, male and female appear quite similar.

In dimorphic species, the males appear quite different from the females.

(Life, the science of biology, 7th edition, chapter 23)

Fish for the most part are not easily sexed, however, some species do have identifying marks or attributes called sexual dimorphism. Species that do not display a difference visually are called monomorphic. To determine the sex of Monomorphic the easiest method is Venting.

Monomorphic and polymorphic, in this context, refer to the shape of the ECG tracing. In monomorphic ("same shape") tachycardia, the QRS complexes all look about the same, indicating that the elevated heart rate is due to electrical signals originating in about the same location in the heart. In polymorphic ("many shape") tachycardia, the QRS complexes look different from each other, indicating that the signals generating the elevated heart rate are coming from various locations in the heart.

I believe that it refers to a site in the chromosome which contains a gene that translates to a feature which appears identical in both males and females of the species.
