the weight of evidence
no sources on either side

In human biology and mammalian genetics, biological females possess an XX sex chromosome complement containing the genetic instructions shared across the species, while male development is triggered by specific genes (such as SRY) typically located on the Y chromosome; however, the core genetic information of the organism is contained within the shared autosomal and X-linked genome.

The analysis

The claim that a female genome contains all the genes needed to produce a male organism is a well-established biological fact regarding mammalian genetics (notably via sex-reversed XX males, such as XX individuals carrying an SRY translocation, or experimental models). While none of the retrieved papers directly discuss XX male syndrome or human SRY translocations, the general biological principle regarding chromosomal determination and the absence of a required citation for basic biological definitions makes this common knowledge. None of the retrieved papers directly support or refute this specific claim as primary evidence.
