Sex Is Not a Spectrum — It's Defined by Gametes
Colin Wright clarifies that biological sex is not a spectrum but is scientifically defined by gamete size: males produce small gametes (sperm), females produce large gametes (ova). Claims that sex is a spectrum often confuse secondary sex characteristics with biological sex itself, which is a category error.
- Biological sex is defined by gamete size, not appearance
- Males produce small gametes, females produce large gametes
- Secondary characteristics like body fat or strength exist on a spectrum but don't define sex
- Intersex conditions are variations within the binary, not a third sex
“There's not a third intermediate gamete between sperm or ova — there's not really a third sex”
