With all due respect I would have thought you would have put in more effort before digging your heels in.Actually there aren’t. A person has either XX or XY. Along with that there are sub variants that are considered uncommon or out of the norm, but the base structure is always XX or XY, there is no XG or CY etc. etc..
Bottom line is you are wrong. Even if you were not your arguement doesn't work;
M: If they’re classed by gender which is determined by chromosomes present there would be 2 divisions.
G: This is simply not true. Although very rare there are several other chromosomal combinations that occour in humans
M: Actually there aren’t. A person has either XX or XY. Along with that there are sub variants that are considered uncommon or out of the norm...
Re "Along with that there are sub variants that are considered uncommon or out of the norm" -
isn't that what I just said? How can you possibly argue that both these sides support the same conclusion?
Re "A person has either XX or XY" and "the base structure is always XX or XY, there is no XG or CY etc. etc.." -
Again, not true. IDK about XG or CY so I'd guess you just made those up or something to illustrate your point. I do know about X , 45,XO , YY , 45X/46Y , XXY and more.
Google term "X and Y chromosome variations" for a shitton of science based links compete with pictures.
Here's some less sciency articles that can be self supported out of the rabbit hole opened by googling as above -
Think gender comes down to X and Y chromosomes? Think again
Humans like to see other humans neatly labelled as male or female. But biology is much less precise, and much more fluid
Chromosomes: Definition & Structure
Chromosomes carry our basic genetic material.
