When people say there are only two sexes, they are typically referring to a binary biological classification based on the primary function in sexual reproduction. In this model:
* Males are defined by their role in producing small, mobile gametes called sperm. They typically have XY chromosomes and reproductive systems adapted for producing and delivering sperm.
* Females are defined by their role in producing large, relatively immobile gametes called eggs (ova). They typically have XX chromosomes and reproductive systems adapted for producing eggs, fertilization, and often gestation.
This binary understanding of sex is rooted in the observation of these distinct reproductive roles across many species, including humans. It focuses on biological attributes such as:
* Chromosomes: The presence of XX chromosomes is typically associated with female development, while XY is typically associated with male development.
* Gonads: Ovaries in females produce eggs, and testes in males produce sperm.
* Hormones: Estrogen and progesterone are often associated with female development, while testosterone is often associated with male development.
* Anatomy: Differences in internal and external reproductive organs.
It’s important to note that while this binary model is common and reflects the majority of the population, it doesn’t account for the existence of intersex individuals. Intersex is an umbrella term for people born with sex characteristics (chromosomes, hormones, gonads, or anatomy) that don’t fit typical binary notions of male or female. These variations are naturally occurring.
Furthermore, it’s crucial to distinguish between sex (a biological construct) and gender (a social and personal construct related to one’s internal sense of self and how they express that identity). While sex is often assigned at birth based on visible biological characteristics, gender identity can be more complex and exist beyond a binary of male and female.

Sex

For purposes of financing the disqualified criteria can be only biological. i.e. birth certificate status of physical sex organs.

Queer

The term queer can have nothing to do with either of these criteria but be in the mind of the beholder as a power to dominate exclude or denigrate a particular person, class of persons or place.
