There&#x27;s enough women in the profession to have female -&gt; female lines originating out of them, though. The implication is that there&#x27;s a huge majority of queer women in them, to the point where heterosexual ones won&#x27;t even show up on a visualization despite how much of a minority GLBT people are in the general population. (Or, alternatively: heterosexual women in those professions don&#x27;t marry for whatever reason, and queer ones do.)
