That's not how it works.

Often things such as color or patterns on animals are not as simple as normal mendelian inheritance, an example is the color of the iris. Colors can depend on many different genes or combinations of versions of genes (alleles). There is many research groups working on color and pattern inheritance in other animals. An example of these "strange" inheritance patterns is the tortoiseshell pattern only seen on female cats (and males with a chromosome number defect).
Genetics or cytology of the Potamotrygonidae family is not the most studied field. However there are a few studies. One study show that there is a difference in the number of chromosomes between male and female stingrays of some of the species, (summarized in my blogpost: http://biologdavid.blogspot.com/2011/06/fresh-water-stingray-facts-different.html). It is possible that some of the genes involved in patterning and color is located on any of these chromosomes and therefore gives a biased pattern from depending on sex or if the pattern is inherited from the male or female. However this is just a qualified guess from my side.
