The hermaphrodite (her) locus has both maternal and zygotic functions required for normal female development in Drosophila. Maternal her function is needed for the viability of female offspring, while zygotic her function is needed for female sexual differentiation. Here we focus on understanding how her fits into the sex determination regulatory hierarchy. Maternal her function is needed early in the hierarchy: genetic interactions of her with the sisterless genes (sis-a and sis-b), with function-specific Sex-lethal (Sxl) alleles and with the constitutive allele SxlM#1 suggest that maternal her function is needed for Sxl initiation. When mothers are defective for her function, their daughters fail to activate a reporter gene for the Sxl early promoter and are deficient in Sxl protein expression. Dosage compensation is misregulated in the moribund daughters: some salivary gland cells show binding of the maleless (mle) dosage compensation regulatory protein to the X chromosome, a binding pattern normally seen only in males. Thus maternal her function is needed early in the hierarchy as a positive regulator of Sxl, and the maternal effects of her on female viability probably reflect Sxl's role in regulating dosage compensation. In contrast to her's maternal function, her's zygotic function in sex determination acts at the end of the hierarchy. This zygotic effect is not rescued by constitutive Sxl expression, nor by constitutive transformer (tra) expression. Moreover, the expression of doublesex (dsx) transcripts appears normal in her mutant females. We conclude that the maternal and zygotic functions of her are needed at two distinctly different levels of the sex determination regulatory hierarchy.

While the lack of black femme presence is theorized explicitly with respect to film genres and the canon of American cinema in the work of Kara Keeling, the ontological position of the black femme (whom Keeling understands to be both visually impossible and interdicted yet full of cinematic possibility) has long been a point of interrogation in Black Studies with an extensive critical genealogy. In Saidiya Hartman's book Lose Your Mother: A Journey Along the Atlantic Slave Route, the loss of the black mother animates the historical imagination of transatlantic slavery, just as her loss is irreducibly felt in relation to its afterlife. In the work of Frank B. Wilderson III, there is an explicit rejection of the potential of the black woman within film, specifically the viability of her maternal function, insofar as the black mother remains categorically essential to the construction of black (masculine) subjectivity. In light of the contradictory arc of this genealogy, the current task is not only to theorize the black maternal as an extension of the black femme, but to bring that position into view as the unthought. The black mother tends to be dramatized as the singular figure through which the cinema cultivates a distinctly black visual historiography. Even when placed under narrative erasure or withheld from view, the mother crystallizes a cinematic black aesthetic that fashions and envisions diasporic culture and forms of black collectivity as tied to a speculative and fraught filial genealogy. The critical arc in black narrative cinema over the last ten years from Get Out to Pariah, to Mother of George, and finally to Moonlight insists upon black motherhood as integral to the aesthetics of form and the genre-making capacities of film. One could go so far as to claim that the elements of cinematic form that drive these narratives reflect aesthetic choices that have to do with coloration, shot position, and narrative flashbacks that are themselves bound up with and inflected through the haunting and cipher-like construction of black maternal figures. Furthermore, these films insist upon simultaneously marking and excluding the mother from the emotional drama of black subjective life and its complex and contradictory expressions of intimacy, which have as much to do with the breaking and splintering of familial bonds as bridging gaps. It is clear that the mother sutures these bonds; she is a scar, a visible reminder and remainder of a terrible historicity that cannot be assimilated into the idealization of the American family.

The beginning of a sharp decline in the birth rate in Europe dates back to the last quarter of the 19th century, the period of the heyday of capitalism, when the exploitation of the working class takes on the most refined forms, the contradiction between the social status of women and her maternal function appears sharper and brighter.
