I am of a species that has 46 chromosomes.
If I have one extra chromosome I am still of the species that has 46 chromosomes.
Despite having 47.
I am not a daffodil or a fruitfly suddenly.
How do we know?
This is because there are other criteria than just this one, chromosomes, that allow me to be categorised accurately and unequivocally excluded from the wrong categories
Almost every human has chromosomes, genitals, reproductive tract and gonads which all are concordant.
There are two varieties of sex.
The male version of these characteristics is easily distinguishable from the female.
If ONE criteria is missing, the others that remain tell the tale.
Absence of one single characteristic is inconsequential.
PRESENCE of ANY opposite sex characteristic is not the same as missing ovaries.
If you leave the postcode off an envelope it still leaves the address remaining.
If you don't have ovaries? your uterus, vagina, clitoris and double X chromosomes tell the remainder of the tale.
Being OF THE CLASS that has several characteristics is as much about being unequivocally excluded from the opposite class by virtue of having none of THEIR defining characteristics.
And it goes without saying, that even if it's been surgically removed it always was and is still your innate characteristic.
People only pretend to be confused about this.
We learn as toddlers which shaped wooden block fits in which shape hole.
We learn how to categorise, which criteria matter (shape, size) and which are irrelevant (colour) to deciding where a block fits.
Adults trying to persuade you it's terribly complicated aren't fooling anyone.
