What is the diffrence (sic)in male and female? That's a question asked at Yahoo Questions. Nice, simple, obvious... except it's none of those.

    Sex can be determined on the basis of several biological criteria:
    1. Genitalia - primary sex characteristics
    2. Secondary sex characteristics
    3. Endocrine (Hormonal) balance
    4. Genes, either XX vs XY, or presence/absence of SrY complex
    5. Neuroanatomy, sexually dimorphic development of the brain.

    None of these are strict binaries though. They all have gradations with 2 distinct peaks, one for female, one for male, but some in the middle.

    The Gender Binary is an excellent approximation, where all 5 criteria align 59 times out of 60. The difficulties begin when we try to make an approximation into an absolute: biologically, this is senseless.
