Nope! Sex is a lot more complex than this and there are many chromosomal configurations and variations.
Do you understand that masculine-looking women and feminine-looking men exist? Do you understand that people with a chromosomal sex inconsistent with their phenotypic sex exist? You might be intersex yourself without realising it. If you’re a man, you might have ovaries and a uterus. Have you ever had a scan to check?
For your information, the following chromosomes/gonosomes have all been scientifically recognised and studied:
- 45, X
- 45,X/46,XY mosaicism
- 46, XX/XY
- 47, XXX
- 47, XXY
- 47, XYY
- 48, XXXX
- 48, XXXY
- 48, XXYY
- 49, XXXXY
- 49, XXXXX
- XX gonadal dysgenesis
- XY gonadal dysgenesis
- XX male syndrome
47,XXY is also known as Klinefelter Syndrome or KS. The extra X chromosome can come from either the father or the mother. Interestingly, only about 25% of people with KS are diagnosed thoughout their lives. You might have XXY chromosomes yourself, right now!
What about 46, XY complete gonagal dysgenesis? A person with that intersex condition is phenotypically female and will generally have normal female external genitalia. Would you still consider them male? What about this case of a healthy and unambiguously female chimera with 46,XX/46,XY karyotype? Still male? https://doi.org/10.1515%2Fjpem.2009.22.1.97
